I've put this here as they are not Windsors, but were descended from the Stuarts (I think from Robert II, but I'm not sure).
I'd like to know more about the Queen Mum's siblings. As you can see from the list they were by no means long-lived. I've never understood why "longevity genes" are always referred to. Fergus was killed in the First World War, and I think it was Michael who was reported killed but turned up a year later (he had been a POW). Any photos?
