I have long forgotten her name, but he indicated that both state and Mormon Church records ignored those of native heritage because of their "lesser" status. His people never converted to the LDS church so they were further excluded from these records. But this heritage was much discussed with pride within the family, especially because of the Cherokee reputation for "high culture"; meaning, having or accepting many of the cultural attributes of Anglo settlers; the creation of villages, a non-transient agricultural economy and later, a written language.
Very late in my own life, I explored my genetic roots via Ancestry.Com and their DNA testing. In a home filled with art depicting Native and Cherokee images and a fair amount of "Indian" jewelry and crafts, I was astounded at the DNA report. No Native blood at all. Lots of English ancestors and blood, but no trace of American Indian heritage. My family story and our discussions were much like Senator Warren's family story. Frustrating for me too that no one on my maternal side were still with us to better understand this disconnect from scientific evidence. I gather than Senator Warren has the same verification dilemma.
I've not decided if she is my candidate, but she seems like a trustworthy leader and I am hoping people will cut her some slack on this issue. She's never claimed tribal participation and has apologized to Cherokee Nation leadership. Let's judge her on her overall character, accomplishments and brilliant policy recommendations to make our lives better.
