Bruce, Robert (fl.1138-1189?) (DNB00)
BRUCE, ROBERT de III (fl. 1138–1189?), second son of Robert II, and so called Le Meschin or the Cadet, was the founder of the Scottish branch. He held the Annandale fief, with Lochmaben as its chief messuage, for the service of a hundred knights during the reigns of David I, Malcolm IV, and William the Lion, who confirmed it by a charter in 1166. He paid escuage for the manor of Hert in the bishopric of Durham in 1170, which he is said to have received from his father to supply him with wheat, which did not grow in Annandale. The date of his death is uncertain, but he must have survived the year 1189, when he settled a long-pending dispute with the see of Glasgow by an agreement with Bishop Jocelyn, under which he mortified the churches of Moffat and Kirkpatric, and granted the patronage of Drivesdale, Hoddam, and Castlemilk, in return apparently for a cession by the bishop of his claim to certain lands in Annandale.
