Earl of Galloway is a title in the Peerage of Scotland. It was created in 1623 for Alexander Stewart, 1st Lord Garlies, with remainder to his heirs male bearing the name and arms of Stewart. He had already been created Lord Garlies in the Peerage of Scotland in 1607, with remainder to the heirs male of his body succeeding to the estates of Garlies. This branch of the Stewart family were distant relatives of the Stewart King of Scotland.
Several other members of the family have also gained distinction. The Hon. John Stewart, third son of the third Earl, was a brigadier-general in the army and also sat as Member of Parliament for Wigtownshire. The Hon. Keith Stewart, third son of the sixth Earl, was an Admiral and Member of Parliament. His son James Alexander Stewart-Mackenzie was Governor of Ceylon. His grandson was James Stewart-Mackenzie, 1st Baron Seaforth. The Hon. Montgomery Granville John Stewart, sixth son of the seventh Earl, represented Kirkcudbrightshire in the House of Commons. The Hon. James Henry Keith Stewart, eighth son of the seventh Earl, was Member of Parliament for Wigtown Burghs. The Hon. Keith Stewart (1814–1859), younger son of the eighth Earl, was an admiral in the Royal Navy. The Hon. Alexander Stewart (1838–1896), third son of the ninth Earl, was a major-general in the army.
The Stewart Baronetcy, of Burray in the County of Orkney, was created in the Baronetage of Nova Scotia on 4 November 1687 for Archibald Stewart. In 1704 the title was inherited by the afromentioned sixth Earl.
The Earls of Galloway are now considered to be the senior branch of Clan Stewart. The family seats are Marchmont House, in West Sussex, and Florence House, in Kenya.
