Dear Mary, Please excuse how long it has taken me to reply. I got error messages for nearly a month. Anyway, Martha RATHMELL CLARKE was born in Northumberland Co., PA and died in Williamsport, Lycoming Co., PA. Her parents are Mary GUILKEY and Amariah RATHMELL, Sr. If you e-mail me directly, I can give you what I know about Martha's ancestors. And descendants, too, if you're interested. Best regards, Amy
