Nicholas Mynn was a servant of the 4th Duke of Norfolk: so much could be deduced from the list of boroughs for which he was returned, all of which were wholly or partially under the duke’s patronage. He is best known as the lawyer whom Norfolk sent to Rome in the spring of 1558 to procure a dispensation for the duke to marry his cousin Margaret Audley; the dispensation had not been issued when Queen Mary died, whereupon the marriage took place and was followed by an Act of Elizabeth’s first Parliament ratifying it. Mynn’s presence in that Parliament was doubtless of advantage to his master’s cause: as a Member of the previous one he can have attended only the first session, being still abroad when the second was held in November.3Williams, 34-35, 77; CSP For. 1553-8, p. 389.
Nothing has been discovered about Mynn’s career before his mission to Rome, nor of the legal training which qualified him for that task, unless he was the ‘Mr. Mynne’ who in 1566 pleaded a special admission for his discharge from office at the Inner Temple. He was to survive his master’s execution in 1572, but of his subsequent career and death nothing has come to light.4Cal. I.T. Recs. i. 241, 463.
