Wife of Macbeth. Ambitious for her husband and willing to do anything to help him steal the crown he wants, even act against her own nature.
Lady MacBeth is loosely based on Gruoch ingen Boite (fl. 1020–1054) was the daughter of Boite mac Cináeda, son of Cináed III. She is most famous for being the wife and queen of MacBethad mac Findlaích (Macbeth). The dates of her life are not certainly known.
Before 1032 Gruoch's first marriage was to Gille Coemgáin mac Maíl Brigti, Mormaer of Moray, with whom she had at least one son, Lulach mac Gille Coemgáin, later King of Scots. Gille Coemgáin was killed in 1032, burned in a hall with fifty of his men. Gruoch of Scotland in WikipediaLady MacBeth in Wikipedia
