I have quite a bit of information dating way back that was given to me by a gr. uncle. It was sent to him by David Diffenderfer, who got it from a Roy L. Diffenderfer. It's interesting reading, but, as always, my John B. is not there. I would think that he probably came from Lancaster Co., but I keep coming up empty handed. I've been stuck on him for 5 yrs. Very frustrating! If you have anything at all, I welcome even slightest possibilities or suggestions.
