Richard III’s descendants are not on the British throne. Richard’s cousin took the throne and his line ended with Elizabeth I who had no descendents.
That is the thought I had nibbling in the back of my head. However, the Daily Mail’s third paragraph reads:
“But it may have also exposed skeletons in the closet of the British aristocracy - undermining the Tudor dynasty - and could even raise a question mark over the current Queen’s royal heritage.”
and it is the last half that I was thinking of. But as others have said, there are the current Windsor’s who are from King George I of Hanover.
