I was one of the original posters here. I started the thread on the Mahlon Family of Clearfield County, PA. I haven't been here for a long time due to some issues going on in my life. It's really interesting to see the information that has been posted here over the years.
You are right about Aaron Dunworth and Susan Porter's decendants. There are quite a few that still live in the Clearfield County area. My mother's family are some of them. My grandmother (Mahlon, Puncious, Dunworth, Porter surnames) is a direct decendant and where I get my lineage from.
My grandfather (Thomas and Spencer Surnames)is buried in a cemetary near Grampion, Rockton and that vicinity. I don't remember the exact location but it may be the same one that Susan Porter is buried in. I've only visited there only a few times throughout my life so my memory is a little sketchy on this.
