Thomas Trevor, 1st Baron Trevor (1658 - 1730), was knighted in 1692 as solicitor-general and in 1695 became attorney-general.
In 1701 he was appointed chief justice of the common pleas, and in 1712 he was created a peer as Baron Trevor of Bromham. On the accession of George I in 1714 he was deprived of the justiceship, but from 1726 to 1730 he was Lord Privy Seal. Three of his sons succeeded in turn to his barony, and a fourth son, Richard Trevor (1707-1771), was bishop of St Davids from 1744 to 1752, and then bishop of Durham.
