Biography

Ermina was born about 1255. She is noticed in some sources as Erminia. She was the daughter of Thomas de Lascelles, Lord of Bolton, and his wife, Christian.

Daughter, and heiress, of Thomas de Lascelles and Christian de Ireby; the Lady that married Robert de Brus the "Competitor", as his second wife.

Sir Bruce Gordon Seton notices her as Daughter of Sir William de Treby of Gamelsby^[1] but this is the same person confirmed by the lands and the marriage to Bruce.

She married Sir John de Seton of Hinderwell near Whitby, Yorkshire, and a knight of Robert Bruce, the "Competitor".

She was certainly still alive when their eldest son, Sir Christopher Seton was executed for treason in 1306. His execution, drawn and hanged, must have taken place just prior to 4 October 1306. There is notice that the manor of Kenreston, in the bishopric of Durham, is held, as dower, to Ermina, widow of John de Seton and assignment by Christopher Seton. His assignment was retained and the dower maintained and the manor granted to the king's servant, Geoffry of Hartlepool and his wife, Anna.^[2]

She, Ermina, is mentioned in a later Charter, relating to the same lands, as being his mother.^[3]

She was still alive in February 1307 but likely died shortly after.

Research notes

Concerning her parents, note that Richardson explicitly states that Ermina the wife of John de Seton was not a daughter of Thomas or of his wife Christiane. According to Douglas Richardson:^[4] Thomas was under age in 1223. He and Christiane had no children. He died shortly before 10 Sep 1260. His first cousin Roger de Mowbray, inherited Bolton manor in co. Cumberland the same year. And Christiane's heirs were not children of hers.
