Fascinating. I knew of her before, but as the article pointed out, the details of her heritage were downplayed, so it has never struck me before just how fraught this situation was, since she was the queen of King George III, the monarch of the American colonies before the American Revolution. It's eerie how this angle must have played into any discussions in the palace about slavery, in the colonies as well as in Britain.
It's also of note that William and Kate gave their daughter her name, Charlotte. They both majored in history and are not strangers to this topic.
