How do I search for the records of Native Americans born during the 18th century? Is this possible? Also, how do I search those that died in movement during the trail of tears or determine if they began identifying as white on Census records? I have a relative that various family has said is Choctaw from Mississippi, but I cannot find her death or birth certificate. Her name may have been Elizabeth "Betsy" Williams before marriage, Elizabeth Perkins afterwards. She may also have been named Laughing Waters (last name unknown).
