Gruoch of Scotland

Gruoch ingen Boite was the daughter of Boite mac Cináeda son of Cináed III. She is most famous for being the wife and queen of Mac Bethad mac Findlaích (Macbeth). The dates of her life are not certainly known.

Before 1032 Gruoch was married 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. The next year one of her male relatives, probably her only brother, was murdered by Malcolm II.

Gruoch is named with Boite and also with Mac Bethad in charters endowing the culdee monastery at Loch Leven. The date of her death is not known.

She served as the model for the character Lady Macbeth in William Shakespeare's play Macbeth. A slightly more accurate version of Gruoch appeared in the animated television series Gargoyles.

She is also a central character in David Greig's 2010 play Dunsinane, in which she is known as Gruach and outlives Macbeth.

Gloria Carreño's 2009 play A Season Before The Tragedy Of Macbeth premiered by British Touring Shakespeare 2010, also sheds a new light on the central character, Gruach Macduff. Based on historical fact the play considers events up to the opening of the letter from the three witches in Shakespeare's tragedy.

Susan Fraser King wrote historical novel about Gruadh - Lady Macbeth: A Novel.
