William Keith, 7th Earl Marischal

William Keith, 7th Earl Marischal (1614 – 1670 or 1671) was a Scottish nobleman and Covenanter.

[1] During the English Civil War, the 7th Earl Marischal joined James Graham, 1st Marquess of Montrose against the Gordons[2] and twice seized Aberdeen in 1639, including a march with Montrose and 9,000 men along the Causey Mounth past Muchalls Castle[3] and through the Portlethen Moss to attack via the Bridge of Dee.

He was appointed a Lord of the Articles after the pacification of Berwick-upon-Tweed, and again seized Aberdeen and enforced signatures of the covenant in 1640.

He subsequently refused to give up fugitives to Montrose, and was besieged at Dunnottar Castle in 1645.

He took no active steps against the popular party until he joined Hamilton's expedition into England in 1648, escaping from the rout at the Battle of Preston, and entertained Charles II at Dunnottar in 1650.
