Andrew Murray was the posthumous son of the Sir Andrew Murray who died of wounds received at the battle of Stirling Bridge (1297). Was a knight by 1320 and a widower (wife’s name unknown) with two sons when, in July 1326, he married Robert I’s widowed sister Christian Bruce. The Bruce family connection probably explains why Sir Andrew was chosen as Guardian of the realm for the young David II [Christian’s nephew] after the death of Donald, earl of Mar at the battle of Dupplin (1332). Murray was captured early in the following year by English forces and the Guardianship passed to others. In 1334 Murray was ransomed and in September 1335 was once again chosen as Guardian. On 30 November 1335 Murray defeated and killed David of Strathbogie, earl of Atholl, Balliol’s northern lieutenant, at the battle of Culblean. For the next two years Murray conducted a notably destructive ‘scorched earth’ campaign against English and Balliol interests across eastern Scotland. He died at his family’s ancestral castle of Avoch on the Black Isles in Lent 1338. Buried at nearby Rosemarkie but his remains were later moved to the Bruce mausoleum at Dunfermline. He left two sons by his first wife, John and Thomas, who inherited his estates. His widow Christian Bruce lived until 1356.
