Brewer Family Genealogy Forum
I'm a descendant of Elvira. I have no information that she had Indian heritage. I can't even prove conclusively who her father was. I think he might be a William and probably kin to Henry Brewer of Nacogdoches, Texas.
There has been some discussion of Indian lineage on the Carnes line. She married Wm. R. Carnes. I have a good many descendants.
I have no proof that there was Indian on that line either, other than tradition from descendants. If someone has information, I would be interested in having it.
