Notes:

"The barony of Corsewall passed to Alexander, Lord Stewart of Garlies, in 1622, and it was confirmed to him by a charter of 1623, two months before he became Earl of Galloway. By the same charter, the king erected a burgh of barony, to be called Stewartoun. This charter was ratified by parliament in 1633. A charter of 14 July 1662, confirmed the possessions of James, earl of Galloway, including the barony of Corswall, with the burgh of barony of Stuartoun. Although there does seem to have been a village of Stewarton in Kirkcolm parish (Groome notes that the parish is sometimes called Stewarton), its site is now unknown. There is testimony, from two independent sources, that Corswall house was wholly ruinous in 1684, and that there was no such place as Stewarton in the parish at that time. The burgh must be written off as never having existed other than on paper." (http://canmore.rcahms.gov.uk/en/site/60723/details/stewarton)
