Augusta Marie of Holstein-Gottorp
Augusta Marie of Holstein- Gottorp( 1649 – 1728) was a German noblewoman.
She was the daughter of Frederick III, Duke of Holstein- Gottorp and Duchess Marie Elisabeth of Saxony.
Through her daughter Albertine Frederica, she is the great- grandmother of Catherine II and great- great- grandmother of Paul I of Russia.
She married Frederick VII, Margrave of Baden- Durlach on 15 May 1670 in Husum.
They had the following children:
Ingeborg of Holstein
Ingeborg of Holstein (1396 – 14 October 1465), was Abbess of Vadstena Abbey 1447-1452 and 1457-1465.
She was the daughter of Gerhard VI, Count of Holstein-Rendsburg (d. 1404) and Catherine Elisabeth of Brunswick-Lüneburg.
In 1408, she was placed in the convent by Queen Margaret I of Denmark by special consent of the Pope.
She became a full member of the order in 1415.
Due to her age, it is believed that she initially resided in her own house on the convent premises.
In 1447, she was appointed Abbess.
Her election was controversial and an active opposition remained against her appointment.
She had the loyal support of the confessor of the abbey, Magnus Unnonis.
Ingeborg was the maternal aunt of King Christian I of Denmark, which was likely the cause to why King Charles VIII of Sweden 25 April 1452
demanded that she and the confessor of the abbey, Magnus Unnonis, should be deposed.
Bishop Nils König of Linköping saw no cause for this, but both Ingeborg and Unnonis stepped down in
May. They were reinstated in their positions in 1457.
Ingeborg worked to install the so-called vårfrupenningen to a regular fee, a goal she succeeded with by permission of Charles VIII of Sweden in 1450, and again from Christian I of Denmark in 1461.
In 1462, she received the papal legate Marinus de Fregeno in Vadstena.
Upon the request of Christian I, she wrote the (C 50, UUB), "Fjorton råd om ett gudeligt leverne" (Fourteen Advises to live goodly), likely before his visit in 1461.
Ingeborg is believed to have supported the Roman side against Conciliarism and the new Papal policy of Concords and diplomacy, and opposed the national centralism of Charles VIII of Sweden.

Catherine Elisabeth of Brunswick-Lüneburg (ca 1367 – after 1423) was Duchess consort of Schleswig and Countess consort of Holstein-Rendsburg.
She was the regent of some of the fiefs of her son Henry during his minority from 1404 to 1415.
She was a daughter of Magnus II, Duke of Brunswick-Lüneburg and Catherine of Anhalt-Bernburg, daughter of Bernhard III, Prince of Anhalt-Bernburg.
Through her mother, she was the great-great granddaughter of King Abel of Denmark.
She would also become the grandmother of Christian I of Denmark.
Catherine Elisabeth was in fact likely named only Catherine; she was often referred to as Elisabeth in older literature, but this was likely due to a mixup with her younger sister, who was named Elisabeth.
In the 14th century, it was still rare to have two first names such as "Catherine Elisabeth".
Due to this confusion, however, she has sometimes been referred to by both names.
Ingeborg of Mecklenburg-Schwerin
Ingeborg of Mecklenburg( 1343/45 – 25 July 1395) was a daughter of Albert II, Duke of Mecklenburg and his wife, Euphemia of Sweden.
Euphemia was a daughter of Ingeborg of Norway, who was the only legitimate child of King Haakon V of Norway.
Thus, Ingeborg of Mecklenburg was Haakon V's great- granddaughter.
In 1360, she married Louis VI" the Roman" of Bavaria; she was his second wife.
The marriage remained childless.
After Louis's death, she married Henry II, Count of Holstein- Rendsburg.
