Neither Pam nor I have listed sons of Seth as Ebenezer Sr or Jr. My Seth ancestor had two children Alice and William. There may have been others but I have not found them.
Pam's ancestor Ebenezer had a brother Seth but at this point we do not know if they are related. It only seems possible. I am returning to Vermont this week to recheck the cemetary where my Seth is buried - perhaps this will yield another clue!
