Descendants of William and Mary A. Palmer of England

I am working on the family of my grandparents Charlie and Anne Palmer. The original Palmers I know are William (Born Oct. 19, 1746) and Mary Alston Palmer (Born in 1756) of CountyKent, England and I will start there. It's more involved than I first thought. I will appreciate all your help. I don't get to work on it as much as I would like. I might not see the messages right away. Thanks!
