David IV Strathbogie
David IV Strathbogie (c. 1332–1369) was an Anglo-Scottish noble who inherited the barony of Strabolgi and the forfeited, titular earldom of Atholl as a small child, after his father David III was killed fighting for Edward Balliol at the Battle of Culblean in 1335.
He married Elizabeth Ferrers and was summoned among the English barons. He died in 1369 leaving only two daughters, so his barony fell into abeyance and his estates were divided between them.
