Context: Nawojka (pronounced: ; 14th-century – 15th-century) was a legendary medieval Polish woman known to have dressed as a boy in order to study at the University of Kraków in the 15th century.  She later became a nun.  She is considered to be the first female student and teacher in Poland. The Daniels County Courthouse, located at 213 Main Street in Scobey, is the county courthouse serving Daniels County, Montana.  The building was built in 1913, the same year Scobey was relocated to a site on the Great Northern Railway, and originally functioned as a hotel.  The two-story building, which had a false front, was the largest in the city at the time.  Over the next seven years, the hotel passed through several hands; it became known as "One-eyed Molly's House of Pleasure" after its most notorious proprietor, a glass-eyed woman known as One-Eyed Molly who supposedly ran a brothel from the hotel.  When Daniels County was established in 1920, the newly formed county purchased the hotel to use as its courthouse. Saint Margaret of Scotland (c. 1045 – 16 November 1093), also known as Margaret of Wessex, was an English princess of the House of Wessex.  Margaret was sometimes called "The Pearl of Scotland".  Born in exile in the Kingdom of Hungary, she was the sister of Edgar Ætheling, the shortly reigned and uncrowned Anglo-Saxon King of England.  Margaret and her family returned to the Kingdom of England in 1057, but fled to the Kingdom of Scotland following the Norman conquest of England in 1066.  In 1070 Margaret married King Malcolm III of Scotland, becoming Queen of Scots.  She was a very pious Roman Catholic, and among many charitable works she established a ferry across the Firth of Forth in Scotland for pilgrims travelling to St Andrews in Fife, which gave the towns of South Queensferry and North Queensferry their names.  Margaret was the mother of three kings of Scotland, or four, if Edmund of Scotland, who ruled with his uncle, Donald III, is counted, and of a queen consort of England.  According to the "Vita S. Margaritae (Scotorum) Reginae" ("Life of St. Margaret, Queen (of the Scots)"), attributed to Turgot of Durham, she died at Edinburgh Castle in Edinburgh, Scotland in 1093, merely days after receiving the news of her husband's death in battle.  In 1250 Pope Innocent IV canonized her, and her remains were reinterred in a shrine in Dunfermline Abbey in Fife, Scotland.  Her relics were dispersed after the Scottish Reformation and subsequently lost.  Mary, Queen of Scots at one time owned her head, which was subsequently preserved by Jesuits in the Scottish College, Douai, France, from where it was subsequently lost during the French Revolution.
