Isabella of Mar
Isabella of Mar was the first wife of Robert Bruce VIII, Earl of Carrick. Isabella died before her husband was crowned King of Scotland. She and her husband were the grandparents of Robert II, King of Scotland.
Isabella was the daughter of Domhnall I, Earl of Mar and Elena, daughter of Llywelyn the Great. Isabella's father was evidently an adherent of Robert Bruce V, Lord of Annandale, a man who staked a claim to the Scottish throne. The close relationship between the Domhnall's family and the Bruces is evidenced by two marriages. One was that between Isabella and Robert Bruce VIII, Earl of Carrick, a grandson of Robert Bruce V. Domhnall's son and comital successor, Gartnait, married a sister of Robert Bruce VII.
The marriage of Robert Bruce VIII and Isabella probably took place in the 1290s. The union produced a single child, a daughter named Marjorie, who was born in about 1296.
Six years after Isabella's death, Robert Bruce VIII married his second wife, Elizabeth de Burgh. Robert and Isabella's daughter, Marjorie, married Walter Stewart, Steward of Scotland, and their son eventually reigned as Robert II, King of Scotland.
