I just started this processes and have no information on my fathers family,besides great grandparents and great aunts. My father has passed. And I can not reach any cousins ect.. I am trying to find out where the Potwins from Iowa originated ect. It seems as if it stops at my dads first cousins. I am a great grand daughter of Edgar Potwin. wife Josafine I believe. Effi for short. If you have any information that you could help me with that would be great.
