"The witnesses to this document [marriage contract between Ellis Price and Anne Humphrey in 1649] were: John ap William ap Humffrey, David John Hugh, Griffith ap Rees Lewis, Edward Vaughn and John ap Hugh. Rowland Ellis, born in 1650, was the only child of Ellis Price (alias ap Rees) and Anne Humphrey, and therefore inherited Bryn Mawr under this settlement and continued to live there until his permanent removal to Pennsylvania in 1696; when he sold the place to Lewis Owen, of Tyddyn y Garreg, his kinsman, to whom he was indebted."
