I know you posted this more than two years ago, but it's worth a shot replying. My grandmother is Mary Alice McNatt. She grew up in Caddo, Olka., but left immediately after she graduated high school and only saw her family a few times years later. Although none of us ever met him, she would mention her youger brother, Billy Ray, when recounting her childhood in Caddo. If this is a coincidence, it's a monsterous one. Please let me know if you read this and if you've discovered anything else about your family tree. Thanks!
