About Isobel MacDougall, of Argyll

Around 1386 both of Ewan's daughters married Stewarts of Innermeath from Perthshire. Janet and Isabella inherited Lorn equally as females under the laws of primogeniture. Then Janet and her husband Sir Robert Stewart traded their half of Lorn to her younger sister Isabella and her husband Sir John Stewart in exchange for Sir John Stewart's inherited estate of Durrisdeer in Perthshire. Through Isabella the Lordship of Lorn then passed to her Stewart husband.

Isabel de Ergadia was the daughter of John of Lorn MacAlan and Jonet Issac.[1],[2] She married Sir John Stewart, Lord of Lorn, son of Sir Robert Stewart.[1] She died on 21 December 1439.[1]
