On a hunch, I logged in to Mendenhall forum hoping to find some information on my family. I, too, am looking for Clarks.
I am searching for Samuel Clark, born 1821 in PA and married to Amanda, also born in PA. I do not have Amanda's last name but recall my mother(a Clark) saying there were Mendenhalls in her line and I am hoping that may be Amanda's maiden name. Samuel and Amanda were last found by me in the 1870 census in Hocking County, Ohio.
By any chance, do you have any information for me?
