On Thursday, someone enquired: “Who had a better claim to the throne than Henry VII”?
The short answer (excluding the right by conquest): almost anyone.
Conventionally, his mother was descended from Edward III through the Beaufort line, but they were only legitimised “excepta dignitate regali”. However, the balance of evidence suggests that his parents were undispensed first cousins, making Henry personally illegitimate. Then again, his great-grandfather, the first Beaufort, may have been a legitimate Swynford, giving him no royal descent at all. According to the latest DNA evidence, this latter conclusion is at least 5% probable.
The long answer: In summer 1485, apart from the reigning King Richard III, his Suffolk nephews all had claims and there were a few of those. Even if we discount women from reigning in their own right, many of his nieces later had sons. His father’s sister, Isobel, was married to an Earl of Essex and had Bourchier issue. His grandmother Anne Mortimer was the last of her line but Richard of Cambridge had a sister, Constance, through whom Anne Neville and the Barons Bergavenny descend. After Anne Mortimer but before Cambridge’s cousins would come the legitimate, unattainted Lancastrians in Portugal. Then there was an Earl of Kent and, as soon as attainders could be reversed, there was an Earl of Warwick and a Stafford heir.
Have we forgotten anyone?
