This family name was brought to Boverton around 1560 by Roger Seys of Cowbridge who married Elizabeth Voss. She inherited Boverton land on which they built a large mansion, Boverton Place. Roger was a lawyer becoming Attorney General for the Principality of Wales under Elizabeth I. He died in 1600 and there is a wall plaque to his memory in St. Illtud’s Church. His descendants were also lawyers, the most notable of whom was Evan Seys, 1604-1685 who was MP for Glamorgan and later for Gloucester.
