Arthur, Prince of Wales was born 8 months into his parents' marriage. Is there any possibility that they consummated the relationship before the official wedding day? Or even that Arthur had a different father? Was it ever suggested by contemporaries or those later?
I was wondering because I was reading about the Princes in the Tower being declared illegitimate, and thinking that someone could have used Arthur's premature birth as an excuse to depose him, if he had become king.
