The great grandsons of Elizabeth and Thomas; Renatus Trenwith and Ezekiell Trenwith married two sisters. Joan and Elizabeth Lanyon the daughters of William Lanyon and Elizabeth Ley alias Kempthorne. William was the son of Edward Lanyon and Margery Chappell and the nephew of Phelype Myliton and John Lanyon.
