I have done some research on the Medders family. James B. Medders was my GreatGrandfather. His father was Theopolis (Not sure about the spelling) Medders, and he had some brothers, one of which was William Medders. If I remember correctly, William married a woman named Lucinda Garrett, and they, along with James B., settled in Oklahoma. I think William lived in the Ardmore area and James B. homesteaded in Washita County near Gotebo. I have some more information about the Medders family if I can find it. My mother remembered a few things about James B. and his family, but she passed away in 1997, so I don't have any connections left. If I can locate it, I will post all the information that I have.
