Died 1306

Sir Christopher Seton, son and heir of John de Seton, a Cumberland gentleman, and his wife Erminia Lascelles, was born probably in 1278, since his age is given in 1299 as twenty-one, in an inquisition into the lands of his deceased father. He did homage for these in October of that year, and was in the service of Edward I at Lochmaben in 1304. In 1305 he came into possession of lands which had been granted by Sir John Seton to Robert Bruce and his wife Christian, who was perhaps a Seton. He had married about 1301 Christian Bruce, sister of King Robert, who was possibly his second cousin.

He was present at his brother-in-law's coronation at Scone in 1306, and saved his life at the battle of Methven later in the same year. According to Dugdale he shut himself up in Lochdoon Castle in Ayrshire, and on the surrender of that castle was hanged as a traitor at Dumfries by order of Edward I. He left no heirs. His widow was in March 1307 in receipt of three pence a day from Edward I for her support at the monastery of Sixhill in Lincolnshire. She was afterwards placed in the custody of Sir Thomas de Gray. His Cumberland estates, with the exception of his mother's dower, were given to Robert de Clifford.
