Edmund Tudor was the third and youngest son of Henry VII Tudor and Elizabeth of York, at birth he was titled Duke of Somerset, born in February, 1499, he died in June, 1500.
However, what I am wondering is what happens if he survives?
Now, let's say his brother Arthur still dies as in otl, and his older brother Henry becomes heir to the throne, and later King Henry VIII, what role might Edmund fill? Who might he marry?
