Lord Thurlow never married and on his death in 1806 the barony of 1778 became extinct, while he was succeeded in the barony of 1792 according to the special remainder by his nephew Edward, the second Baron. The latter was the son of the Right Reverend Thomas Thurlow, Bishop of Durham from 1787 to 1791. Lord Thurlow gained a reputation as a minor poet. In 1813 he married the actress Mary Catherine Bolton, and they had three sons. In 1814 he assumed by Royal licence the additional surname of Hovell, in commemoration of his ancestor Sir Richard Hovell.
His grandson, the fifth Baron (who succeeded his elder brother), was a Liberal politician and served as Paymaster-General in 1886. in 1873 he assumed by Royal licence the additional surname of Bruce, which was that of his father-in-law, James Bruce, 8th Earl of Elgin. One year Lord Thurlow assumed by Royal licence the additional surname of Cumming.
In 1952, to pay the death duties of his father the Sixth Baron, Henry Charles Hovell-Thurlow-Cumming-Bruce, 7th Baron Thurlow sold the family house in Surrey, Baynards Park. It was later owned by helicopter entrepreneur Alan Bristow, under whose ownership the Grade II listed Elizabethan-country house burnt down in 1980.
