Green Family of Florida

I am researching my Green family line. My 3xgreat grandfather was Tom, Thomas, or Thomas J(possibly Jefferson) Green. He lved in Dixie and Lafayette counties of Florida. I think he was born in either Wales or England between 1800 and 1812. I have been unable to find his parents' names or that/those of his wife/wives. My line is through his son Frank(lin) Green who married Sarah F B Murphy. Then their son martin Van Buren Green who married Ada Lavonia Higginbotham. They lived in Old Town in Dixie County, FL. My email is mikeglsc@yahoo.com if any one has any information on ths family.
