Who was Henry Tudors son?

Henry VIII only ever had one legitimate son, Edward (to Jane Seymore, his 2nd wife) who did take the throne but died a few years later to be succeeded by his elder sister Mary, who was later succeeded by Elizabeth I.

Henry was reputed to have other sons through his mistresses though. Henry Fitzroy, whose mother was Elizabeth "Bessie" Blount. Fitzroy was made Duke of Richmond in 1525 in what some thought was Henry's first step in legitimatising him. Fitzroy died three years after his marriage to Mary Howard in 1533, while the King was trying to pass a law that would allow his otherwise illegitimate son to become King.

Henry Carey (Mary Boleyn's son) was never acknowledged, as Henry's other illegitimate son was, although there is high speculation that he was also Henry's biological child.
