Cherokee genealogist Twila Barnes posted census data on her blog this weekend that she says shows that Warren’s mother, Pauline Herring, listed herself as “white” in 1940.

Barnes also posted a death certificate for Warren’s “Aunt Bea,” who was listed as “white” on the form. Elizabeth Warren’s name is listed on the death certificate.

The Democratic candidate once famously cited her Aunt Bea’s characteristically Native American “high cheekbones”as evidence of her American-Indian ancestry.
