Your original post was taken directly from Closer Magazine. That’s not exactly Burke’s Peerage. It is what it is; Diana was a commoner although a member of the aristocracy. That is how she came to the attention of the royal family to begin with. A commoner does not mean that she or any of the other women were “common.” Merely that they were/are not members of the royal family. Once she married Charles, she became a member of the royal family.
I certainly know the implications of the word “commoner” in the Brit system. You are missing my point about the difference between manmade titles and biological bloodlines, nor did I plagarize any post from Closer Magazine (GailA posted it, I merely commented on it as posted); but it doesn’t matter. You like to debate in black and white, absolute terms. I am more interested in shades of meaning. Therefore we may rarely agree on matters of historical dispute, such as whether or not Queen Charlotte was actually part black or whether it was the fake news of the day. Either is possible, but I really don’t care about it. Religion is what matters.
