OK, there was a single shred of truth. His daughter’s great or great-great grandparents may have been slaves. Whoop-dee-doo! My great-great-great Scottish grandparents were just barely more than slaves to the land holders in Scotland and England. The first American-born generation in every line of my family sent boys off to fight to free the black slaves here. And I do mean boys. A 15 yr old in one case.
The greater probability is his muslim side was probably involved in trading of slaves....
