Biography Born in Scotland. Walter married in 1233, Ada de Galloway, daughter of Lochlann of Galloway. She was the sister of Alan of Galloway.

Walter fled to Ireland and then to England with his nephew John Byset after they had been accused of involvement in the murder of Padraig, Earl of Atholl (his cousin in-law) and two companions at their lodgings after a tournament at Haddington in 1242. Patrick II Earl of March, exhorted by David de Hastings, pursued Walter who sought protection from King Alexander II of Scotland.
