as you likely know Catherine of Aragon first wife of King Henry VIII was briefly married to Henry's older brother Arthur, Prince of Wales, before Arthur's death, wether or not Catherine and Arthur slept together during this brief marriage became a big issue during Henry VIII's try to divorce Catherine, it is said that the wait before making Henry (then Duke of York) The Prince of Wales (10 months) was due to a belief that Catherine was pregnant with Arthur's posthumous child, turned out of course she wasn't and it can never clearly be known if she was a virgin at the time of her marriage to Henry VIII, but what if Catherine had Arthur's baby? what differences if it was a son vs if it was a daughter?
