Hi, My name is Leticia and I would like to know about my birth father's side of the family. I don't know much except that his name is Eulalio Rangel; he married Josefina and had 2 children, me and my brother Danny in Oklahoma. I want to know where he came from and his ethnic background. My mom is from Oaxaca so I am Mexican/Hispanic but I look American Indian. I'm just wondering if I am any part Indian. I would like to tell my daughters, 1/4 Commanche more about their family history. Any info would be appreciated. Thanks.
