My immediate family starts reliably with John, born in 1789
As stated on home Ancestry page, the living have been omitted.
I think this John had three older sisters, Grace, Elizabeth and Jane, and parents John and Grace, who married in 1770 and lived in or near Chumleigh, Devon.
Tim P: The info I have for Henry is born 11 Mar 1856 (in Upton Pyne, Devon) and died 5 Oct 1924 (in Wallasey, Cheshire). I think that Janet Curran - or her husband (?) - are descended from him. By the way, while Henry was William and Mary's firstborn son, I believe he was actually their 4th child, coming after Elizabeth (1850), Emily (1852) and Edith (1853).
