That is early. 1809 is the year for the earliest source I have for my line, a marriage record in Harrisburg Dauphin County PA. There is another Fronk Family that moves from eastern PA to Beaver County PA, and some of them move to Ohio, but I'm not sure how early they did that and I find no Samuel mentioned. I know that there may be two other Fronk families that went from PA to Ohio, but at this point, it's only other folks like you working their way back to PA through records. I will keep looking at what I have and please let me know if you find Samuel's parents in PA.
