Do you have children's names besides the daughter Ann? I see 2 baptisms in Morpeth that are close in the years you are looking at. Thomas Fenwick born 7 Jan 1793, baptised 24 Mar 1893 s/o George and Ann, then another Thomas Fenwick born 18 Jan 1795 and baptised 13 Mar 1795 s/o Edward and Alice. Janis
