From The Royal Stuarts: A History of the Family That Shaped Britain, Allan Massie writes:

"Monmouth may never have legitimately borne the name of Stuart; yet in person and fortune, he was in many ways characteristic of that remarkable family: he charmed easily, inspired devotion, failed his followers, showed himself to be possessed of lamentable judgement, and ran headlong to misfortune.  He was Stuart through and through; Stuart to the bone."

This promises to be good.
