 Alan de Lauder was dead by 20 March 1407 when Robert is recorded as "executor testamenti quondam Alani de Lawedre patris sui nuper defuncti".As Alan de Lawedre's eldest son and, so, the eldest grandson of Sir Robert de Lawedre of The Bass he was placed in "fee" by his grandfather in the feudal barony of The Bass and its lands, as well as the castle of Edrington, Berwickshire, and that estate.Because of his father's longevity he continued to be often referred to as "of Edrington", even after he was placed in fee of The Bass.
