Strathearn

The Strathearns were the native Gaelic mormaers, later earls, of Strathearn in southern Perthshire, first attested around 1115. Malise I led the men of Strathearn under David I at the Battle of the Standard in 1138.

Malise V succeeded his father in 1329 and inherited the Norwegian jarldom of Orkney, including Caithness. He commanded a Scottish division against Edward Balliol at Halidon Hill in 1333, after which Balliol forfeited his earldom and granted it to John de Warenne.

Malise never recovered Strathearn: David II regranted it to Maurice de Moravia in 1344. The Gaelic line ended with Malise, who died around 1357 leaving only daughters. Through his daughter Isabella, who married William St Clair, the Orkney inheritance passed to the Sinclair family; Isabella and William's son Henry became jarl in 1379.
