And free BLACK slaveowners...
There was a “Different World” episode, a black comedy, that introduced me to this concept. The flighty upper class black woman had her genealogy traced because it was a fad, and found out that her black ancestors owned black slaves. She called up a modern day descendant, said it was from geneology, then when asked how they were related, she said, “My family ... uh, um, owned your family, and that might be how we’re related.”
