Thanks, Noel, for your reply. Your Janet and John are not likely to be mine -- my Janet Gibb didn't marry until 1850, and had a child in 1872, so not likely to be yours born in 1811. The John I am looking for would likely be born about 1805, and would have had his first child about 1825-1830. The identity of John's wife, Isobella Gardiner, also remains unknown to me. Thanks again for your reply.
