Patrick V, Earl of March
Patrick Dunbar, Earl of March (c. 1285–1369), was a leading Scottish magnate under Robert the Bruce and David II, succeeding his father in 1309. He changed sides several times before finally supporting the Scottish cause; in 1338 his wife Agnes Randolph, the famed Black Agnes, defended Dunbar Castle against an English siege.
When his brother-in-law John Randolph fell at Neville's Cross in 1346, Dunbar took the Earl of Moray title. He backed a revolt against David II in 1363 and died in 1369.
