Thank you Caerfai and Maggie for your information. At least I now know I am on the right track.
Maggie, on your tree does it show Anne's marriage to anyone, in particular Joseph Adams c1758-1830. I found some information that shows that Anne and Joseph had at least 11 children, Samuel, Joseph, Richard, Joseph (again), John, William, Anne, Mary, Margaret, Eliza, Jane. One of these children will be my 2x Great Grandparent and is the missing link to my Great Grandmother, Margaret Mary Elizabeth Adams b1849, d1904, and who married James William Naulls 1845-1924.
Regards
Claire.
