John, only child of Francis II and his first wife Margaret of Brittany, was born in June, 1463 and died later that year. WHat if he had survived? With a male heir, would Francis II of Brittany consider marrying again, if so, and Anne of Brittany is still born, how does this influence politics of the region and France? With Francis having a male heir, Anne becomes a marginally less attractive prospect for a french marriage would it not? Who might John marry, what might he become under his father?
