Prince Charles Edward book (1900) by Andrew Lang. Clementina Maria Sophia Walkinshaw (1720 - November 1802), mistress of Prince Charles. Clementina was the youngest of the ten daughters of John Walkinshaw of Barrowhill (1671-1731) and his wife Katherine Paterson. The Walkinshaws owned the lands of Barrowfield and Camlachie, and her father was a wealthy Glasgow merchant (founding the textile village of Calton). He was an Episcopalian and a Jacobite who fought for the Prince's father in the rising of 1715, was captured at the Battle of Sheriffmuir, before escaping from Stirling Castle and fleeing to Europe. In 1717, he was pardoned by the British Government and returned to Glasgow, where his youngest daughter was born probably at Camlachie. However, Clementina was largely educated on the Continent, and later converted to Roman Catholicism. In 1746, she was living at the home of her uncle Sir Hugh Paterson at Bannockburn, near Stirling. The Prince came to Sir Hugh's home in early January 1746 where he first met Clementina.
