Hi. If you send me your e-mail address, I will send you my Wileman gedcom. Clarkson was the son of Jesse W., who was brother to my g.g.g. Grandmother, Mary (Polly) Wileman. So, we are cousins.
The Wileman family were came from England to Pa. They were Wildmans. Abraham Wildman married Letitia Janney in Pa., and they moved to Va. In 1803 the family came to Columbiana Co., then to Stark Co., Ohio.
Do you have records on the descendants of Clarkson? I don't even have the names of his children.
Please e-mail me with your e-mail address, and I'll send the gedcom.
