Facts and Events
Christian (or Christina) de Brus (c. 1278 – 1356/1357) was a sister of Robert the Bruce, King of Scots. It is probable that she and her many siblings were born at Turnberry Castle in Carrick to Marjorie, Countess of Carrick, and her husband Robert de Brus, jure uxoris Earl of Carrick. Christina is often erroneously thought to have married Gartnait, son of Donald, Earl of Mar (died 1305), but recent scholarship questions this because Christina is never described as a countess of Mar, or even described as 'of Mar'. Christina married firstly Sir Christopher Seton who was born in 1278 and executed in 1306), and married secondly in 1326 Sir Andrew Murray born a posthumous child in 1298 of the Sir Andrew Murray who was joint victor of the battle of Stirling Bridge with William Wallace. Sir Andrew died in 1338.
Along with King Robert I's other female relatives, she was captured shortly after his rebellion. Unlike her sister Mary and Bruce's supporter Isabella MacDuff, Countess of Buchan, both of whom were imprisoned in cages, Christina was sent to a convent at Sixhills in Lincolnshire, England.
In 1335, during the Second War of Scottish Independence, she commanded the garrison of Kildrummy Castle and successfully held the castle against pro-Baliol forces led by David of Strathbogie, prior to their defeat by her husband, Sir Andrew Murray, at the Battle of Culblean.
