I've got an awful lot of Northumberland people in my tree. Farnsworth, Saxton, Barthololmew, Bloom, Miller, Dunkelberger, Wolverton, Knoebel, Wintersteen, Welsh, Paine, Inns, Connelly, Shadle, Leisenring, Troutman, Gonsar, Phillips. Those are all direct lines, but I also have some info on other families if they were neighbors. Several members of my family still live in that area, and I have ongoing contact with them, which makes research a little easier. Also, my family kept extremely good records back into the 1700s. I do have more on the Farnsworth/Saxton/Wolverton lines back into NJ. Just let me know what else you need, I'm happy to share!
