In 1649 Robert Tichborne, a nephew of Richard Tichborne, petitioned the House of Commons in favour of the execution of Charles I. He was one of the Commissioners who, in 1651, prepared the way for the union with Scotland; he was knighted in 1655 by Cromwell, and was elevated to the peerage in 1657. After the Restoration of the monarchy in 1660, he was arrested and sentenced to death, but was reprieved, imprisoned in Dover Castle and died, in 1682, in the Tower of London. The family, however, did not die out in Cowden until 1708, when the last member of the family, John Tichbourne, was buried there.
