I'm trying to find out some the Davis family history and out family memebers. I do not know if they are on the roll or not. My grandpa just died and I don't know anything about where my family is from here in Oklahoma. How do I go about trying to find information on my family. I know that my grandpa is a full blood choctaw and his name is Henry T. Davis, Sr.  His parents are Patterson and Lizzie Thompson Davis. How do I research it? Please let me know how to do this. Finding information will help me out.
