The following are given passages.
Passage 1:
Frederick Henry, Margrave of Brandenburg-Schwedt
Frederick Henry, Margrave of Brandenburg-Schwedt (21 August 1709, in Schwedt – 12 December 1788, in Schwedt) was the last owner of the Prussian secundogeniture of Brandenburg-Schwedt.

Early life
His was the son of Margrave Philip William, son of Philip William, Margrave of Brandenburg-Schwedt and his wife Sophia Dorothea of Schleswig-Holstein-Sonderburg-Glücksburg. His mother was Princess Johanna Charlotte of Anhalt-Dessau, daughter of Prince John George II of Anhalt-Dessau and Princess Henriette Catherine of Nassau.

Life
After his father's death in 1711, his mother put Frederick Henry under the guardianship of his uncle Frederick I, and after Frederick I's death in 1713, under the guardianship of his cousin Frederick William I.  In 1711, Frederick Henry was made the chief of the Infantry Regiment No. 12.  However, he showed little interest in military affairs.  In 1733, King Frederick William I was so incensed with the disorder in Frederick Henry's regiment that he was jailed for several weeks.  Frederick the Great held little respect for Frederick Henry's abilities and did not employ him.  In 1741, Frederick Henry traded the Infantry Regiment No. 12 for the Infantry Regiment No. 42, but again, he cared little for his duties, and he left its business to the respective commanders.
When his brother Frederick William died in 1771, Frederick Henry inherited the Lordship of Schwedt-Wildenbruch.  As "Margrave of Brandenburg-Schwedt", he was a patron of the arts, especially theater.  In 1755 he acquired the Prinzessinnenpalais in Berlin and in 1785, he contracted the actress Henriette Hendel-Schutz to perform in his Court Theater.
He married his first cousin Leopoldine Marie of Anhalt-Dessau, a daughter of Prince Leopold I of Anhalt-Dessau, nicknamed the old Dessauer.  After the birth of two daughters, he and his wife quarreled so often and so violently, that he banned her to Kolberg for the rest of her life.
Between 1760 and 1762, the mathematician Leonhard Euler sent numerous letters in French about mathematical and philosophical subjects to his daughter Frederike. These letters were published between 1769 and 1773 under the title "Letters to a German Princess" and were printed in Leipzig and St. Petersburg. The French edition alone enjoyed 12 printings. It was the Age of Enlightenment and Euler tried to explain physical issues and in particular their philosophical background in a generally understandable manner. Frederick Henry may have employed Euler as her teacher.When he died in 1788, the junior line of Brandenburg-Schwedt died out and the secundogeniture fell back to the Electorate.  His daughters and nieces received a pension.

Daughters
Louise of Brandenburg-Schwedt (10 August 1750 – 21 December 1811) married Prince (later Duke) Leopold III of Anhalt-Dessau (1740-1817)
Friederike Charlotte of Brandenburg-Schwedt (18 August 1745 – 23 January 1808), the last Abbess of Herford Abbey
Passage 2:
Princess Anna Elisabeth Louise of Brandenburg-Schwedt
Princess and Margravine Anna Elisabeth Louise of Brandenburg-Schwedt (German: Luise; 22 April 1738 – 10 February 1820) was a Prussian princess by marriage to her uncle Prince Augustus Ferdinand of Prussia. She was a daughter of Margrave Frederick William of Brandenburg-Schwedt and Princess Sophia Dorothea of Prussia.

Early life
Anna Elisabeth Louise was one of five children born to Margrave Frederick William of Brandenburg-Schwedt and Sophia Dorothea of Prussia. Her siblings included Sophia Dorothea, Duchess of Württemberg, and Philippine, Landgravine of Hesse-Cassel.
Her father was a son of Philip William, Margrave of Brandenburg-Schwedt and Princess Johanna Charlotte of Anhalt-Dessau.
Her mother was a daughter of Frederick William I of Prussia and Sophia Dorothea of Hanover. Through her mother, Anna Elisabeth Louise was a niece of Frederick the Great.

Princess of Prussia
On 27 September 1755 in Charlottenburg Palace, Berlin, Anna Elisabeth Louise married her uncle Prince Augustus Ferdinand of Prussia, a younger brother of her mother, Sophia Dorothea. He was eight years older than she and was a younger son of Frederick William I of Prussia and Sophia Dorothea of Hanover (herself the only daughter of George I of Great Britain).

The biological father of her daughter Louise, who was born in 1770, may have been Count Friedrich Wilhelm Carl von Schmettau. Louise was described as nice, witty and kind. The Swedish Princess Hedwig Elizabeth Charlotte described her at the time of her visit in 1798: In the afternoon, we visited this Princess, who lives at Bellevue in the outskirts of Berlin. It is a little villa, very suitable for a private person but far from royal. The reception here was quite dissimilar from the one at my aunt. Princess Ferdinand is stiff and made it obvious that she wished to impress us. I was of course polite, but after I had noticed, that she took on a condescending tone and wished to embarrass me, I replied the same way and displayed the same haughtiness. The Princess is no longer young, has surely been beautiful, looks like an aristocratic Frenchwoman but not like a Princess, for she has nothing royal about her. I do not think she is that clever, but she can make a pleasant conversation and is quite confident, as one becomes through a long habit of socializing in the grand world. 
Anna Elisabeth Louise was one of the few members of the royal house to remain in Berlin during the French occupation in 1806. While most of the royal family left, reportedly because of the anti-Napoleonic criticism they had expressed, and the members of the royal court either followed them or left the capital for their country estates, Elisabeth Louise remained with her spouse and Princess Wilhelmina of Hesse-Kassel because of "their great age", as did Princess Augusta of Prussia, who was pregnant at the time.One visitor to her in 1813–14 commented that, "I never saw such a formal, stiff, disagreeable old woman - vieille cour outree, and she frightened me to death. I was glad to get away...".

Death
Augustus Ferdinand died in Berlin on 2 May 1813. Elisabeth Louise died seven years later, on 22 February 1820. She is buried in Berlin Cathedral.

Issue
On 27 September 1755 in Charlottenburg Palace, Berlin, Anna Elisabeth Louise married her uncle Prince Augustus Ferdinand of Prussia
The couple had seven children:

Friederike Elisabeth Dorothea Henriette Amalie, Princess of Prussia (1761–1773)
Friedrich Heinrich Emil Karl, Prince of Prussia (1769–1773)
Friederike Dorothea Louise Philippine, Princess of Prussia (1770–1836), married to Prince Antoni Radziwiłł
Heinrich Friedrich Carl Ludwig (1771–1790)
Friedrich Ludwig Christian (1772–1806)
Friedrich Paul Heinrich August, Prince of Prussia (1776)
Friedrich Wilhelm Heinrich August, Prince of Prussia (1779–1843)

Passage 3:
Frederick William, Margrave of Brandenburg-Schwedt
Frederick William of Brandenburg-Schwedt (17 November 1700 – 4 March 1771) was a German nobleman. In his lifetime, from 1711 to 1771, he held the titles Prince in Prussia and Margrave of Brandenburg, with the style Royal Highness. He was made a knight of the Order of the Black Eagle.
In the 19th century he was retrospectively known by the title Margrave of Brandenburg-Schwedt, in order to differentiate his branch of the Hohenzollern dynasty.  He was the second owner of the Prussian secundogeniture of Brandenburg-Schwedt. His parents were Philip William, Margrave of Brandenburg-Schwedt, and Princess Johanna Charlotte of Anhalt-Dessau. He was the nephew of King Frederick I of Prussia.

Life
Frederick William was known as a brutal man because of his short temper, severity, and coarse manners. He was born at Oranienbaum Castle (modern-day Oranienbaum-Wörlitz, Wittenberg), and was educated and raised by his uncle, King Frederick I, and then by his cousin, King Frederick William I. His character closely resembled that of his second royal guardian, who like himself, hated idleness and was a terror to all loungers. The clergy were especial objects of his ridicule and persecution. His cane was as much feared as that of his royal namesake.He made the fashionable Grand Tour, travelling to Geneva 1715, and in 1716 to Italy. He returned in 1719 to Prussia, where he received the Order of the Black Eagle from Frederick William I. On 15 June 1723 he was made a Prussian major-general. On 10 July 1737 he was appointed lieutenant-general.The existence of the Schwedt branch of the Hohenzollern dynasty, descended as they were from Frederick I's father and being 'princes of the blood', posed a theoretical threat to the Prussian kings.  Frederick William I tried to neutralise this threat by keeping his cousins close, bringing the Schwedt brothers into his own household, acting as their guardian, and later marrying Frederick William to his daughter. Following the margrave's reaching adulthood the king was so fearful of any covert political activity on his cousin's part that he sent spies to Schwedt to find out who met with Frederick William and his brother.Margrave Frederick William pursued a lavish programme of building in Schwedt, both in the palace and town, and he actively purchased land and estates to augment his inheritance; this aggrandisement resulted in the king eventually forbidding him from making any more such purchases. In contrast to his father's policy Frederick II sought to distance himself from his Schwedt cousins, humiliating them at every chance. He made them unwelcome at his court, undermined the margrave's authority in his own dominions by encouraging complaints and lawsuits by his tenants and neighbours and, most effectively, he marginalised the position of the Schwedt brothers within the Prussian army.  Margrave Frederick William was removed from command in the army, a denigration the king also extended to his own brothers.Frederick William was 19 years older than his wife Sophia Dorothea of Prussia, who was his first cousin once removed.  The marriage, in 1734, was at the express wish of King Frederick William, against the wishes of his daughter; the bride was given away by her brother the future Frederick II, as the king was unwell. The relationship of the couple was not happy. Sophia often fled to the protection of her brother King Frederick. The latter did not stop at friendly admonitions, but sent General Meir to Schwedt with unlimited authority to protect the margravine from insult. Eventually they lived in separate places: Sophia lived in the castle Montplaisir, and the Margrave lived in the castle of Schwedt. Apparently they were only reconciled when the margravine was in her terminal illness; she died in her husband's arms.On 4 March 1771, Frederick William died at Wildenbruch Castle, when the heavy cold he was suffering from worsened. The Margrave acknowledged one illegitimate son, the only one of his male offspring to survive infancy. Due to his lack of surviving legitimate male issue, his lands and title were inherited by his younger brother Frederick Henry (ruled 1771–1788).

Issue
In 1734, the Margrave married Sophia Dorothea of Prussia and they had five children.
Sophia Dorothea (18 December 1736 – 9 March 1798); married Frederick II Eugene, Duke of Württemberg
Elisabeth Louise (22 April 1738 – 10 February 1820); married her uncle Prince Augustus Ferdinand of Prussia
George Philip (10 September 1741 – 28 April 1742)
Philippine (10 October 1745 – 1 May 1800); married Frederick II, Landgrave of Hesse-Kassel (or Hesse-Cassel)
George Frederick (3 May 1749 – 13 August 1751)He also fathered an illegitimate son named Georg Wilhelm von Jägersfeld (1725–1797).

Genealogy
Frederick William belonged to a junior branch of the House of Hohenzollern; the senior branch were the Counts of Hohenzollern-Sigmaringen. The junior line produced electors of Brandenburg and kings and emperors of Prussia and Germany. Frederick William was a descendant of Burkhard I, Count of Zollern. Through his daughter Sophia Dorothea he is an ancestor of Mary of Teck (Queen Mary), the wife of George V, and therefore an ancestor of the present British royal family.

Passage 4:
Charles Frederick Albert, Margrave of Brandenburg-Schwedt
Karl Friedrich Albrecht, Margrave of Brandenburg-Schwedt (10 June 1705 – 22 June 1762), a grandson of Frederick William of Brandenburg (the Great Elector) and son of Margrave Albert Frederick of Brandenburg-Schwedt, was a Prussian military officer and the Herrenmeister (grand master) of the Order of Saint John (Bailiwick of Brandenburg).

Life
Charles of Brandenburg-Schwedt was born in Berlin. He joined the Prussian Army at an early age and distinguished himself during the First Silesian War at the capture of Głogów, at the Battle of Mollwitz and the Battle of Chotusitz. He took command in Upper Silesia in the spring of 1745, to the special satisfaction of his cousin, King Frederick II of Prussia.
During the Seven Years' War Margrave Charles again held independent commands, as Frederick II had confidence in him, and he distinguished himself at the Battle of Hochkirch and the Battle of Torgau. In both battles, as at Mollwitz, he was wounded.
The General German Biography (ADB) describes him as a noble, philanthropic character and lover of the arts and sciences.
For 31 years he governed the knights, the Bailiwick of Brandenburg, and its fiefs as Grand Master of the Order of St. John, having been installed at Sonnenburg in 1731. He died in Breslau.

Issue
Charles Frederick Albert was never married, but had one daughter with his mistress, Dorothea Regina Wuthner (who was raised to the nobility on 14 January 1744 as "Frau von Carlowitz"):

Caroline Regina von Carlowitz (Soldin, 12 December 1731 – Berlin, 16 September 1755), married in Berlin on 16 June 1747 to Count Albrecht Christian von Schönburg-Hinterglauchau (22 January 1720 – 9 March 1799), Charles's adjutant. They had three children:Countess Ernestine Caroline Wilhelmine Albertine of Schönburg-Hinterglauchau (6 June 1748 – 21 March 1810); married in Berlin on 2 November 1770 to Count Frederick Louis Finck von Finckenstein (18 February 1745 – 18 April 1818).
Count Frederick William Charles Ernest of Schönburg-Hinterglauchau (9 January 1751 – 17 June 1751).
Count Christian William Charles Frederick Ernest of Schönburg-Hinterglauchau (14 June 1752 – 9 March 1770).In 1744, Charles was engaged to marry Maria Amalia of Hesse-Cassel (1721–1744), but she died before they could wed.  Upon his death in 1762, lacking legitimate heirs, his estate reverted to the crown.  After the Treaty of Hubertusburg, Frederick II granted these fortunes to the two officers for whom he had particular gratitude: Hans Sigismund von Lestwitz received the estate of Friedland, and Joachim Bernhard von Prittwitz, who had led the king from the battlefield in the Kunersdorf, received the estate at Quillitz.  Theodore Fontane gave this circumstance a special mention, by quoting a proverb:   "Lestwitz a sauvé l'etat, Prittwitz a sauvé le roi." (Lestwitz saved the state, Prittwitz the king.) The staff officers of the Lestwitz regiment received a golden medal.

Passage 5:
Charles Philip of Brandenburg-Schwedt
Margrave Charles Philip of Brandenburg-Schwedt (5 January 1673 in Sparnberg – 23 July 1695 in Casale Monferrato) was a Hohenzollern prince and a titular Margrave of Brandenburg-Schwedt. Near the end of his life he became Grand Master of the Order of Saint John (Bailiwick of Brandenburg).

Life
Charles Philip was the third surviving son of the "Great Elector", Frederick William of Brandenburg (1620–1688) from his second marriage with Sophia Dorothea (1636–1689), the daughter of Philip, Duke of Schleswig-Holstein-Sonderburg-Glücksburg.In 1693, Charles Philip proved himself at the Battle of Neerwinden and was promoted to Lieutenant General by his brother Frederick I. He participated in the War of the Palatine Succession at the head of an auxiliary contingent.  He joined the main force of Victor Amadeus II of Sardinia in Turin.In Turin, he met Countess Caterina di Salmour (1670-1719), widow of Giovanni Gabaleone, Count di Salmour and daughter of Geofredo Alberico Balbiani, Marchese di Colcavagno by his wife, Marta-Maria Benso di Cavour, heiress of Isolabella. On the afternoon of 29 May 1695 three officers of Brandenburg's army, Col. Ludwig von Blumenthal, Lt. Col. von Hackeborn and Col. von Stille learned that Charles Philipp had lodged in the recently ruined Palace of Venaria, near Turin, where he was about to marry the Countess di Salmour in secret. They hurried towards La Venaria. As they neared the château, the Margrave’s Master of the Horse met them on the road and confirmed the rumour. The Margrave had invited a small gathering to his secret wedding, including three women who were friends of the Countess, her brother Flaminio Balbiano, and some local Torino notables; on the German side were a Prince of Hesse-Cassel and a Captain Beaupré, currently serving in Brandenburg’s army. The local priest Fr. Galli was summoned, and before him and in the presence of Abbot Alexander del Marro and the Chevalier Parella, they declared their determination to marry. But the priest refused to co-operate on the grounds that they were not his parishioners. The Abbot and Captain Beaupré fought; Staff intervened and the Margrave then fell upon the Master of Horse with drawn sword, who fled.Riding on, the three colonels came upon the Margrave, heading for the Countess’ house in Turin in his carriage with his escort. They joined the cavalcade, and when they reached the destination the Prince’s advisors implored him not to carry on. Neither the Elector of Brandenburg, nor the Duke of Savoy recognized the marriage. To avoid diplomatic complications, Duke Victor Amadeus imprisoned Caterina in a convent. The Curia supported Charles Philip's claim that the marriage was legal, in the hope that he would convert to Catholicism.  While the issue was still being debated, Charles Philip died of a fever or (it was said) of a broken heart. He was buried in the Hohenzollern family crypt in Berlin Cathedral.
Two years later, Rome ruled that the marriage was valid.  The Elector still did not recognize it.
In 1707, Caterina married the Saxon general Count August Christoph von Wackerbarth.

Passage 9:
Philip William, Margrave of Brandenburg-Schwedt
Philip William, Prince in Prussia (German: Philipp Wilhelm von Brandenburg-Schwedt; May 19, 1669, castle of Königsberg – December 19, 1711, castle of Schwedt) was a Prussian Prince,  was the first owner of the Prussian secundogeniture of Brandenburg-Schwedt and was governor of Magdeburg from 1692 to 1711.

Biography
Philip William was the eldest son of the Great Elector and his second wife, Princess Sophia Dorothea of Schleswig-Holstein-Sonderburg-Glücksburg. One of her major endeavours was to ensure the financial security of her sons, mostly by the purchase of land. Shortly after the birth of Philip William, he was invested with his mother's dominion of Schwedt, later, the Brandenburg-Prussian government added the lands of Wildenbruch. Both dominions were improved by Princess Dorothea's care and investments. Following the death of his mother, Philip, in an accord of dating to 3 March 1692, reached agreement with his half-brother, the Elector Friedrich III, about income and lands left to him by the Great Elector, including the lordship, without sovereignty, of Halberstadt. Philip received for himself and his descendants guaranteed appanages generating an income of 24,000 thalers each year. Added revenue came in to the amount of 22,000 thalers from the rule of Schwedt, plus military salaries of about 20,000 thalers, so that with a total income of 66,000 crowns he was enabled to hold court, in some style, himself.
He held, like all the male members of his house, the courtesy title, Margrave of Brandenburg. After the coronation of his elder brother, Frederick, he became Prince in Prussia, Margrave of Brandenburg with the style Royal Highness. The nomenclature "Brandenburg-Schwedt" came into use in the 19th century, posthumously, to distinguish the lords of Schwedt from the main line of the Hohenzollerns. Philip William was the ancestor of the Schwedt branch of the Royal House of Hohenzollern. On 25 January 1699 Philip Wilhelm married Princess Johanna Charlotte of Anhalt-Dessau (1682–1750), daughter of John George II, Prince of Anhalt-Dessau. As a widow she became Abbess of the Imperial Abbey of Herford.
Philipp Wilhelm served as a general in the campaigns against France and was promoted in 1697 to Inspector-General of the artillery. His half-brother, Prince Elector Friedrich III (later King Frederick I of Prussia), also gave him the proprietorship of several regiments. During his time as governor of Magdeburg, he was raised by the University of Halle (Saale) to the post of "Rector magnificentissimus”.
Philip's Berlin residence, the Margrave Weilersche Palace, was later used by Kaiser Wilhelm I. He was buried in the Berlin Cathedral, where most of the senior members of the House of Hohenzollern are buried.
Since Philip's eldest son, Frederick William, was a minor at his death, the King of Prussia (Frederick I and Frederick William I) took over guardianship. With the death of his granddaughter, Anna Elisabeth Luise, the collateral line of Brandenburg-Schwedt became extinct in 1820.
