But are we sure none of them thought they were black?
Rachel Dolezal has no genealogical claim whatsoever that she is black, going back through the last four centuries, an investigation by Daily Mail Online has revealed.
The woman who sparked a national debate on race has no black relatives dating back to 1671; in fact her family were entirely white including some who were Mormons.
Archives show that Rachel’s ancestors came to the US from Europe and have no bloodlines linking them to slaves or Africa.
Even a great grandmother who has almost identical features to Rachel was identified as white in two census documents.
Our reporters commissioned Massachusetts-based genealogist Elizabeth Banas to look into Rachel’s past to see if her heritage was indeed as her parents described.
Ruthanne and Larry Dolezal, from Troy, Montana, said in interviews that Rachel was a mixture of Swedish, German and Czech heritage with a little Native American.
Our findings support their claims and show that Rachel has no black lineage even though she has defined herself as African American in her job applications.
Miss Banas said: ‘I did not see anything in the records to indicate a connection to an African bloodline’.
Meanwhile, the fake sister was — get this — outraged to discover white actors playing African characters. Yes, really.
Instead of the media fawning over this mental patient, isn’t it time for an intervention?
