Strathbogie
The Strathbogies were a semi-Normanized Gaelic family from Fife, named for their lands at Strathbogie in Aberdeenshire. John de Strathbogie married Ada, Countess of Atholl, and their son David became Earl of Atholl in 1264.
The ninth earl, John, was captured fighting for Scotland at Dunbar in 1296, then joined Robert the Bruce's rising and died in English reprisals after the 1306 coronation. His son David sided with England, and the earldom was forfeited in 1314.
David III became a chief lieutenant of Edward Balliol and won restoration under his brief kingship, but was killed at Culblean in 1335. His son David IV kept the claim until his death in 1369 without ruling Atholl, which passed first to the Campbells and later to the Stewarts.
