His father, William Harcourt Isham Mackworth (1806—1872), a younger son of Sir Digby Mackworth, the 3rd Baronet, took the additional surname Dolben after he married Frances, the heiress of Sir John English Dolben, the 4th Baronet.
His oldest son, Metcalfe, survived him by only four days, the baronetcy then passing to his second son, Tancred, who became a Rear Admiral of the White and was twice Lord Mayor of York.
