Gospatric de Dunbar, 1st Earl of Dunbar; living c1115, when he seems to have been a signatory to the Charter of Scone by which the Abbey of Scone was founded; killed leading his men of Lothian in Scottish defeat by the English at the Battle of Standard (near Northallerton, North Yorks) 23 Aug 1138. [Burke's Peerage]

EARLDOM OF DUNBAR (I)
GOSPATRIC DE DUNBAR, EARL [SCT], 3rd son being younger brother of Dolfin (expelled 1092 from Carlisle), was apparently one of the nine signatories to the charter of Scone (circ. 1115), as also, about a year later (under the style of Gospatricus, frater Dolfini), to the Inquisitio Davidis. He appears to have held the position of an EARL, though there is no record of the title of the Earldom, nor is he ever called Earl in any known document in his lifetime. In a charter, confirmed 16 August 1139 (after his death), to the monks of Durham, he is styled "Gospatricus Comes, frater Dolfini," being, in the heading thereof, called "Gospatricus secundus Comes frater Dolfini." This Earl is doubtless the summus dux Lodonensium (the leader of the men of Lothian) slain at the battle of the Standard 22 August 1138, fighting against the English at Cowton Moor, near Northallerton.
