My ggg-grandparents were George Dalby and Frances Wymond. I have some information on them but have not had much luck with any of the children outside of a few birth dates. My line in the family comes from Elizabeth Dalby who married Samuel Kirby. Samuel was married to Elizabeth in 1856 and at a later date she died and he remarried. He came to the United States and brought his children with him but I believe at the time he was a widower once again.
I believe the Dalby line goes back to John Dalby/Mary Bates, George Dalby/Sarah Barnett, John Dalby/Ann Freer, and George Dalby/Dorothy Fletcher.
