(1357 – c. 1386), Prince of Scotland, was a 14th century Scottish magnate. He was the eldest son of the second marriage of King Robert II of Scotland
with Euphemia de Ross
. King Robert, on 26 March 1371, the day of his coronation, is styled Earl of Strathearn
, and on the following day his son David does homage to him under the title of Earl of Strathearn.Acta Parl. Scot.
, i. 545.
On June 19 of the same year, he obtained a charter of the barony
, iv. pp. cxvi, clix; Reg. Mag. Sig.
, fol. ed., 122. He received the Castle of Braal
21 March 1375, and he was also given the title Earl of Caithness
between that date and 28 December 1377, when he was styled "Earl Palatine of Strathearn and Caithness".Reg. Mag. Sig.
, fol. ed., 150.
He was involved in a major dispute with his older half-brother, Alexander Stewart, Earl of Buchan
, who by 1385 had occupied his castle at Urquhart
. It is uncertain, but it is highly likely that he died in March 1386, and no later than 1389. His wife appears to have been a daughter of Sir Alexander Lindsay of Glenesk
, and sister of David Lindsay, 1st Earl of Crawford
. They had issue a daughter, Euphemia Stewart, Countess of Strathearn
, who succeeded to the earldom as Countess in her own right.
