I've always liked this scene from The Ten Commandments. It would explain most of the points you made.
At one point during the Exodus, Moses had a Black Wife.
His sister Miriam made a stink about it, and God struck her with leprosy for a couple of days.
In the running commentary behind this movie, the commentator posits that this Nubian lady was Moses Black wife, but that didn’t occur till much, much later in the story.
This Lady was a captive Princess who seemed to have a crush on her captor, much to the jealous chagrin of Nefertari.
Gosh I LOVE that movie! LOL!
