Alice Comyn, Countess of Buchan
Alice Comyn (1289–1349) was the eldest daughter of Alexander Comyn, Sheriff of Aberdeen, and niece and heiress of John Comyn, Earl of Buchan. In 1310 she married the English baron Henry de Beaumont, who claimed the earldom in her right; his long struggle to secure Buchan helped cause the Second War of Scottish Independence.
Through her daughter Isabel she was great-grandmother of Henry IV. She died on 3 July 1349, when the Comyn line of Buchan came to an end.
