England had an unfortunate young Prince John who was the youngest brother of Queen Elizabeth II’s father and the Duke of Windsor (the guy who resigned). The young man had epileptic fits and was sent to a country estate to get him out of the way, he was an embarrassment to the royals. The King and Queen Mary visited him only rarely. They kept any mention of him out of the news. He died approx. age twelve of an epileptic fit. His only playmates were the children of his caretakers. There’s a documentary about him on You Tube.
