His grandson was Adam Walays who in turn had two sons, the eldest of whom succeeded to the family estates in Ayrshire. Adam's younger son was Malcolm Wallace who received the lands of Auchinbothie and Elderslie in Renfrewshire. Malcolm Wallace appears in the Ragman Rolls of 1296 paying allegiance to Edward I of England, however later he was one of the few Scottish nobles who refused to submit to Edward and as a result he and his son, Andrew, were executed.
