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.
