Thomas de Brus

Sir Thomas de Brus (c. 1284, Carrick, Ayrshire – 17 February 1307) was a son of Robert de Brus, 6th Lord of Annandale and Margaret, Countess Of Carrick and thus a younger brother of King Robert I of Scotland. He supported his brother in the struggle against the English conquest, ultimately being captured by the MacDoualls at Loch Ryan, Galloway, Scotland and later executed by the English.

Thomas was married to Helen Erskine.
