Thomas Fairfax, 3rd Baron Fairfax of Cameron (1612-1671), was commander of the Parliamentary New Model Army during the English Civil War. Following the surrender of the Isle of Man in 1651, he was appointed Lord of Mann by Parliament. He appointed William Christian (Illiam Dhone) as Governor of the Island in 1656, the only Manx-born person ever to hold that title, though Christian was replaced by James Chaloner in 1658.
