Mary II, Countess of Menteith was a Scottish noblewoman. Her father was Alan II, 7th Earl of Menteith,[1] who died c. 1330 and her mother is known only as Marjory. She is believed to have agreed with her kinsman Muireadhach III, in 1330, that he should hold the Earldom,[2] but when he was killed in August 1332, Mary assumed the title.
