Child(ren):
Walter Comyn, Lord of Badenoch, jure uxoris Earl of Menteith (died 1258) was the son of William Comyn, Justiciar of Scotia and Mormaer or Earl of Buchan by right of his second wife.
Walter makes his first appearance in royal charters as early as 1211–1214. In 1220, he accompanied King Alexander II of Scotland during the latter's visit to York. He appears as "Lord of Badenoch" as early as 1229, after the defeat of the Meic Uilleim by his father.
Like his father, Walter was given the hand of an heiress, Isabella, Countess of Menteith. By 1234, Isabella had inherited the Mormaerdom of Menteith, and so Walter became Mormaer or Earl of Menteith by right of his wife (jure uxoris). [1]
Walter appears to have had a son named Henry who witnessed a charter, dated to 1250, of Maol Domhnaich, Mormaer of Lennox. His daughter Isabel was given in marriage to Gilchrist Mure.
