Her brothers defended her, stating that they "grew up listening to our mother and grandmother and other relatives talk about our family's Cherokee and Delaware heritage". The New England Historical Genealogical Society found a family newsletter that
alluded to a marriage license application that listed Elizabeth Warren’s great-great-great grandmother as a Cherokee,
but could not find the primary document and found no proof of her descent. The Oklahoma Historical Society said that finding a definitive answer about Native American heritage can be difficult because of intermarriage and deliberate avoidance of registration. Former colleagues and supervisors at universities she worked at stated that Warren's ancestry played no role in her hiring. In her 2014 autobiography, Warren described the allegations as untrue and hurtful.
