What would happen? Of course this would require Elizabeth to not be sexually abused by Katherine Parr's new husband, in order for her to even consider marriage (and she still might not, who knows). What if Henry had arranged marriages/betrothals for Mary and Elizabeth before his death? Mary was about 31 and Elizabeth 14 when he died, but maybe he does it once he realizes he cannot sire any more children (perhaps by 1544 or 45, since by this point he'd have clearly been too gout ridden to get Katherine Parr pregnant). Who would Mary and Elizabeth marry? I imagine Henry wouldn't be too keen on having Mary get married to Philip of Spain, since he was the grand-nephew of the wife he spent so much time trying to divorce, Mary's tragic Spanish mother. Would these marriages help the survival of the Tudor dynasty? Or at least Henry's bloodline? I'd be interested to see if they can keep the Tudor red hair as well since it's a staple for them. Who would Edward marry as well? He was too young to make any marriage arrangements, so it's anyones guess
