WYNDHAM O’BRIEN, Percy (?1723-74), of Shortgrove, nr. Saffron Walden, Essex.

Succeeding as a minor to the name and estates of the Earls of Thomond, O’Brien was returned for Taunton on the Wyndham interest at a by-election in 1745 soon after he came of age. Voting for the Hanoverians in 1746, he was put down by the Government as a ‘New Ally’. In 1747, when his Taunton seat was required for his elder brother, Sir Charles Wyndham, he ‘forced himself’ into Minehead as a courtier, getting ‘everything that money could buy’, without consulting the lord of the manor, who had a ‘natural interest’ there.H. C. Maxwell-Lyte, Dunster Castle, i. 232-3. In the new Parliament he was classed, with his brother, as a government supporter. He died 21 July 1774.
