On his death the title passed to his eldest son, the third Baronet. He was also a Member of Parliament for Newcastle-upon-Tyne. He was succeeded by his son, the fourth Baronet.

When he died the title was inherited by his son, the fifth Baronet, who was raised to the peerage as Viscount Ridley in 1900.
