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 Wars of Scottish Independence, ultimately being captured in the Battle of Loch Ryan and later executed.
Thomas was married to Helen Erskine.
