So, this is one thing I've wondered a lot about recently, in 1177, Henry the Young King and his wife Margaret of France had a son named William, however said son died a few days later. What I am wondering is, if said son had survived and lived into adulthood, what would've changed?
Would the accusations against Margaret have been made in 1182 if she had given birth to a healthy male heir?
Would Henry still have gone to war with Richard in 1183 and died of dysentery? If not would he have played a part in the wars of his brothers against their father that eventually saw Henry II die in 1189?
If Henry the Young King had still died, would William have been confirmed as Henry II's successor in Normandy and England? Would there still have been rebellions in 1189? What would his uncles Richard, Geoffrey and John have thought of the boy? Who might've served as his regent?
