Somerled Macmillan writer of the book Clan Macmiland is of the opinion that Gilbert was progenitor of the Galloway branch of Macmillans when the occasion of his coming south arose when he and some of his clansmen acted as an escort to Robert the Bruce in 1306, after he had been defeated by the MacDougalls at Tyndrum.
Three years later,in 1309, Gilbert is styled as the Baron of Ken.
