Yes, pretty much like this. The big deal is that the queen Catherine of Valois (wife of deceased king Henry V and mother to king Henry VI) had a love affair with her knight Owen Tudor. They had at least five children. They may have possibly wedded secretly, but there is no ducumented proof of this. What really makes the whole matter spectacular is that Catherine of Valois was a French princess and she was treated with a great deal of suspicion by the English (the 100 years war was still going on). It is amazing how they still managed to keep the whole affair (that could well have ended in the execution of Owen, the children, and possibly even the queen) secret. It is also remarkable how unpopular Richard III must have been for the English to accept the claim of Owen Tudors son who became king Henry the VII (father of Henry VIII. They obviously weren't very creative about names).
Go ahead Nick.
