Beyond his implication along with his father in the quarrels with the Abbot of Melrose, there is little to be learned of Gilbert, the eleventh Laird. He married Barbara M'Dougall, his cousin, daughter of the Laird of Makerstoun ; and is said to have been present with Hugh Earl of Ormond at the battle of Sark, in 1450, and to have afterwards joined the Earl of Angus against the Earl of Douglas, in 1455.
