She married
John Comyn, but he died in
France in 1242. They do not appear to have had issue. A husband was needed to control the dispersed
earldom; she then married
Gilbert de Umfraville, a
Norman, who was feudal baron of
Prudhoe in
Northumberland. He died shortly before 13 March 1245, but not before Matilda had borne him a son named
Gilbert to succeed to the earldom in his infancy: • Gilbert, married Elizabeth Comyn, daughter of
Alexander Comyn, Earl of Buchan, had issue. He died in 1308. Matilda married again before 22 December 1247, Richard de Dover, the feudal baron of
Chilham,
Kent, the son of
Richard FitzRoy (an illegitimate son of King
John of England and his mistress
Adela de Warenne). Matilda disappears from records after producing two children: • Richard of Chilham, Lord of Chilham. He died before 10 January 1266. • Isabel, married
David I Strathbogie, Earl of Atholl, son of John de Strathbogie and
Ada, Countess of Atholl, had issue. ==References==
