The single most boring person to appear in the diary.
Mackworth (yawn!) is "possibly" a son of Col. George Mackworth, who would have known Mountagu from Cromwell's Council of State. He also served on the Treasury Commission -- the father that is, not the son.
The son, you say? Oh. Well. We don't actually know anything about him. If he even is the son of (yawn), Colonel ... ah, what was his name?
