Sacked Dumbarton in revenge of his father (letter from Philip B. Stewart, 6 Sabal Ct., Sewall's Pt., Stuart, Fl., 4/24/1990).
Sir James Mhor Stewart, son of Murdoch, Duke of Albany, was born about 1400 presumably at Duke Murdoch's Castle, Loch Ard, Aberfoyle, Perthshire, Scotland. Sir James Mhor fled to Antrim, Ireland to escape the vengeance of King James I. However, his widowed mother and his sister were spared the King's wrath and remained in Scotland. It is clear that Sir James of Albany probably remained in contact with his mother and sister. In Ireland, James became involved with a woman surnamed MacDonald, believed to be a daughter of Iain Mor Tanistair MacDonald, 1st Earl of Antrim, himself son of John MacDonald, Lord of the Isles and Earl of Ross. This marriage makes more sense when one realizes that John MacDonald, Lord of the Isles, was married to Margaret Stewart, sister to Robert Stewart, 1st Duke of Albany. Thus Sir James Mhor Stewart's "life partner" was his first-cousin, once-removed. This could also explain why they never legally married.
Sir James Mhor Stewart and his life-partner, the Lady MacDonald, never married, but they are believed to have had a family of seven children (another account gives seven sons and several daughters), although evidence of their children is unclear and conflicting. James remained an exile for the rest of his life and died in Ireland, however his son, James Beag Stewart was able to secure a royal pardon and return to Scotland. James Beag was given the property of Baldorran in Campsie parish, Stirlingshire, about twenty miles south of his grandfather's residence of Doune Castle. James' story continues further below (The Stewarts of Balquhidder)
