Earl of Angus

After the death of Mormaer Maol Chaluim, in probably about 1240, the mormaerdom passed through the marriage of his daughter Matilda, to the line of the Norman Gilbert de Umfraville.

The lands of Clan Ogilvy, in Angus, was ruled by a mormaer; one of the ancient Celtic nobles of Scotland who became the first earls.

[2] Gillebride, Earl of Angus, received a Barony from King William the Lion in 1163,[3] and bestowed upon his son, Gilbert, the lands of Wester Powrie, Ogilvy, and Kyneithin.

Robert's heir Gilbert continued attempting to recover the earldom and supported Edward Balliol and other disinherited barons and lords in Scotland.

The Countess secured a charter of her estates for her son, to whom in 1389 the title was granted by King Robert II.

All his other titles devolved to his distant cousin the 7th Duke of Hamilton, whose descendants hold them still.
