I have a William TREWIN born 18 Dec. 1795 in Kilkhampton. His mothers name was Grace TREWIN (maiden name unknown) This Grace TREWIN married or remarried to William BRENTin Kilkhampton on 25 Dec.1799. She may of been unwed at the time of William's birth in 1795. In your message you mention a John TREWIN marrying a Joan, then a Grace ASHTON. Do you know if John and Grace happened to have a William born in 1795 by any chance ? If not, are you aware of any other Grace TREWIN's from Kilkhampton giving birth to a William in Dec 1795?
