What if the baby born to the Duke of Kent and his German wife Victoire of Saxe-Coburg on May 24, 1819 had been a boy? Let us suppose that the prince was christened Alexander. His uncle, King George IV, jealous of his brother's potency, would almost certainly have refused to allow the child to take the dynastic name of George. No doubt the death of his father when the baby was only eight months old would have been followed by a rift between his mother and her brothers-in-law, George IV and the future William IV, and the little boy would have grown up, as Victoria did, in seclusion at Kensington Palace.
In spite of her Saxe-Coburg genes, Victoria was by nature and physique a Hanoverian. I will assume that Alexander inherited this dominant trait: he was Queen Victoria with a Y chromosome.
