Well, we have to remember that Henry, Duke of York did have a better track record with his children. You have Elizabeth, Henry, Edmund, Margaret and Edward from his first wife (Eleanor of Austria) and then Thomas, Cecily, Anne, Catherine, Hannah, Robert, Arthur and Charlotte by his second (Amalia of Cleves). I mean, Arthur didn't do as well child wise (out of 11 children only 4 survived) and who can forget the marriage between King Arthur II and his aunt (Charlotte of York)? And Duke Henry II of York, he was the one who went crazy and killed his family, right (I can't remember if it was him or his son)?
