Viscount Boyne, in the province of Leinster, is a title in the Peerage of Ireland.[1] It was created in 1717 for the Scottish military commander Gustavus Hamilton, 1st Baron Hamilton of Stackallan. He had already been created Baron Hamilton of Stackallan, in the County of Meath in 1715, also in the Peerage of Ireland.[2] Hamilton was the youngest son of Sir Frederick Hamilton, youngest son of Claud Hamilton, 1st Lord Paisley (from whom the Dukes of Abercorn descend), third son of James Hamilton, 2nd Earl of Arran (from whom the Dukes of Hamilton descend). His grandson, the second Viscount, represented Newport (Isle of Wight) in the House of Commons. His first cousin, the fourth Viscount, sat as a member of the Irish House of Commons for Navan.
His great-grandson, the seventh Viscount, married Emma Maria Russell, sister and heiress of William Russell of Brancepeth Castle, County Durham, children of Matthew Russell of the same, and in 1850 assumed by royal licence the additional surname of Russell.[3] In 1866, he was created Baron Brancepeth, of Brancepeth in the County of Durham, in the Peerage of the United Kingdom. Prior to the passing of the House of Lords Act 1999, the Viscounts Boyne sat in the House of Lords in right of this title. As of 2010[update] the titles are held by the seventh Viscount's great-great-great-grandson, the eleventh Viscount, who succeeded his father in 1995.
The family seat is at Burwarton House, near Bridgnorth, Shropshire.
