3. Isabella MAR, daughter of Sir Donald MAR and Helen of Wales, had the title 'Lady of Mar'. She appeared in the census. She died before 1302. She married Robert I Bruce KING OF SCOTLAND.


Isabella of Mar (modern Scottish Gaelic: Iseabail) (c. 1277 ¨C December 1296) was the first wife of Robert the Bruce and the grandmother of Robert II of Scotland, founder of the royal House of Stuart. She died before Robert was crowned King of Scots, and never became Queen.

She was the daughter of Domhnall I, Earl of Mar and a woman named Helen (or Ellen) (1246¨C1295), who had previously been the wife of Maol Choluim II, Earl of Fife. Her father was one of the seven guardians of Scotland who believed Robert Bruce to be the rightful King of Scotland. Despite the considerable risks, the Earl of Mar could foresee the advantage of the two families joining in marriage and bearing an heir to the throne, and the marriage of Isabella and Robert was arranged. Mar was the first to sign over the estates of his family to the Bruce.

Isabella was married to Robert at the age of 18 and legend has it that they were much in love. Shortly after their marriage Isabella became pregnant. She had a healthy pregnancy but she died soon after giving birth to a daughter, Marjorie Bruce in 1296.
