His eldest son, the second Baron, sat as a Liberal Member of Parliament for Beverley and Scarborough.

However, the viscountcy and the earldom became extinct on the death of his grandson, the fourth Earl, in 1937.

The barony was inherited by the late Earl's second cousin once removed, the sixth Baron.

On his death this line of the family failed, and the title passed to his first cousin, the seventh Baron.

As a male-line descendant of the first Marquess Conyngham, he is also in remainder to this peerage and its subsidiary titles.
