My mother's family tree includes a number of names such as Naquin, Picou and Billiot, all common among Indian-French families in central and south Louisiana (and those ancestors lived in parishes where members of the Houma tribe were known to reside).
Have I ever claimed to be part "Native American"? No. But I'll bet I could put forward a more convincing case than Warren.
At least I have a picture to back mine up....Liawatha Warren can only say “My mommy told me!!!”
