Context paragraphs:
John de Cheam: John de Cheam [Cheyam] was a 13th-century English cleric who became Bishop of Glasgow.  Before attaining Glasgow, he had previously been the archdeacon of Bath and a papal chaplain.  In the summer of 1259, after the quashing of the election of Nicholas de Moffat, Pope Adrian IV provided John to the see, and he was consecrated soon after at the Roman court without any consultation with the Glasgow canons.  His election was opposed by King Alexander III of Scotland, who sent a protest to Pope Alexander IV.  The pope refused to revoke the decision, but promised to make John render fealty to the king.  Bishop John arrived in Scotland in the year 1260.  When the mother of the king, Marie de Coucy, fled from her second husband John de Brienne (a.k.a. Jean d'Acre), the Grand Butler of the King of France and the son of John de Brienne, King of Jerusalem, Bishop John was used by King Alexander to reconcile them.  Bishop John was one of the witnesses to the Treaty of Perth on 2 July 1266.  However, his good relations with the king did not make up for the resentment felt by the Glasgow canons at an outside appointee, and John eventually resigned his see in 1267, and went to France.  He died at Meaux the following year, and was buried there.

Baron Greenwich: Baron Greenwich is a title that has been created twice in British history.  The first creation came in the Peerage of Great Britain in 1767 when Lady Caroline Townshend was made Baroness Greenwich, in the County of Kent, with remainder to the male issue by her second husband, Charles Townshend.  She was the daughter of Field Marshal John Campbell, 2nd Duke of Argyll, who had been created Earl of Greenwich in 1715 and Duke of Greenwich in 1719, titles which became extinct on his death in 1743.  As Caroline's two sons by her second husband predeceased her, the title became extinct upon her death in 1794.

Memory of Azov (Fabergé egg): The Memory of Azov (or the Azova Egg) is a jewelled Easter egg made under the supervision of the Russian jeweller Peter Carl Fabergé in 1891 for Tsar Alexander III of Russia.  It was presented by Alexander III as an Easter gift to his wife, the Czarina Maria Feodorovna.  It is currently held in the Kremlin Armoury Museum in Moscow.

Nikolai Bunge: Nikolai Khristianovich Bunge (Russian: Никола́й Христиа́нович Бу́нге ; 23 November [O.S. 11 November] 1823 , Kiev – 15 June [O.S. 3 June] 1895 , Tsarskoye Selo) was the preeminent architect of Russian capitalism under Alexander III.  He was a distinguished economist, statesman, and academician of the St. Petersburg Academy of Sciences.

First Hen (Fabergé egg): The First Hen egg or Jeweled Hen egg is a Tsar Imperial Fabergé egg.  It became the first in a series of more than 50 such jeweled eggs made under the supervision of Peter Carl Fabergé for the Russian Imperial family.  It was delivered to Tsar Alexander III and given to his wife Maria Feodorovna in 1885.  The tsarina enjoyed the egg so much that Alexander III quickly placed a standing order with Fabergé to create a new egg for his wife every Easter thereafter, requiring only that each egg be unique and that it contain some kind of "surprise" within it.  This particular egg is now a part of the permanent collection of the Fabergé Museum in Saint Petersburg, Russia.

Pyotr Ilyich Tchaikovsky and the Belyayev circle: Pyotr Ilyich Tchaikovsky's relations with the group of composers known as the Belyayev circle, which lasted from 1887 until Tchaikovsky's death in 1893, influenced all of their music and briefly helped shape the next generation of Russian composers.  This group was named after timber merchant Mitrofan Belyayev, an amateur musician who became an influential music patron and publisher after he had taken an interest in Alexander Glazunov's work.  By 1887, Tchaikovsky was firmly established as one of the leading composers in Russia.  A favorite of Tsar Alexander III, he was widely regarded as a national treasure.  He was in demand as a guest conductor in Russia and Western Europe, and in 1890 visited the United States in the same capacity.  By contrast, the fortunes of the nationalistic group of composers known as The Five, which preceded the Belyayev circle, had waned, and the group had long since dispersed; of its members, only Nikolai Rimsky-Korsakov remained fully active as a composer.  Now a professor of musical composition and orchestration at the Saint Petersburg Conservatory, Rimsky-Korsakov had become a firm believer in the Western-based compositional training that had been once frowned upon by the group.

Nikolai Kulikovsky: Nikolai Alexandrovich Kulikovsky (5 November 1881 – 11 August 1958) was the second husband of Grand Duchess Olga Alexandrovna of Russia, the sister of Tsar Nicholas II and daughter of Tsar Alexander III.

Princess Olga of Hanover: Princess Olga of Hanover and Cumberland (German: "Olga Adelaide Louise Marie Alexandrina Agnes Prinzessin von Hannover und Cumberland" ; 11 July 1884 – 21 September 1958) was the youngest daughter of Ernest Augustus, Crown Prince of Hanover (1845–1923) and Princess Thyra of Denmark (1853–1933), the youngest daughter of Christian IX of Denmark (1818–1906) and Louise of Hesse-Kassel (1817–1898).  Olga was a great-great-granddaughter of George III of the United Kingdom (1738–1820) and Charlotte of Mecklenburg-Strelitz (1744–1818).

Alexander Comyn, Earl of Buchan: Alexander Comyn, 2nd Earl of Buchan (died 1289) was a Scoto-Norman magnate who was one of the most important figures in the 13th century Kingdom of Scotland.  He was the son of William Comyn, jure uxoris Earl of Buchan, and Marjory, Countess of Buchan, the heiress of the last native Scottish Mormaer of Buchan, Fergus.  He was the chief counsellor of Alexander III, King of Scots for the entire period of the king's majority and, as Scotland's leading magnate, played a key role in safeguarding the independence of the Scottish monarchy.  During his long career, Alexander Comyn was Justiciar of Scotia (1258–89), Constable of Scotland (1275–89), Sheriff of Wigtown (1263–66), Sheriff of Dingwall (1264–66), Ballie of Inverie (in Knoydart) and finally, Guardian of Scotland (1286–89) during the first interregnum following the death of Alexander III.
