The Hamilton baronetcy, of Silvertonhill in the County of Lanark, was created in the Baronetage of Nova Scotia in 1646 (or in 1642, according to Cokayne, see note) for Robert Hamilton, a Royalist and favourite of Charles I. He was a descendant of Alexander Hamilton of Silvertonhill, brother of James Hamilton, 1st Lord Hamilton (ancestor of the Dukes of Hamilton and the Dukes of Abercorn).[1]
