Mulling’s origins are obscure. His date of his admission to the freedom of Canterbury, an essential prerequisite to civic office, is not recorded, but it is likely that his family were already established in the city when he was chosen as cofferer at Michaelmas 1430. Mulling quickly became one of the city’s elite and in May 1434 was among those who took the oath against maintenance administered throughout the realm.
In 1445 Mulling was chosen to be burgess for Canterbury in the Parliament summoned to Westminster. By ‘consideration of the 12 jurats’ he and his fellow MP William Osbourne were paid a daily wage of 1s. rather than the customary 2s., although as this long Parliament sat for 190 days they each received £9 10s. with an additional 10s. for the days spent travelling.
Little evidence survives of Mulling’s private or business affairs and his occupation is uncertain. In May 1436, when he was among a group of Canterbury men indicted for invading the close of St. Augustine’s abbey while making their annual visit to St. Lawrence’s hospital to give alms, he was described as a haberdasher, as he was to be again in 1448,
Mulling made his will on 30 Sept. 1456. He asked to be buried in the cemetery of St. Augustine’s abbey next to his mother, while leaving 3s. 4d. for his obit at his parish church, that of St. Elphege, where masses were to be sung for his soul and those of his parents and benefactors for two years after his death. He also left small sums to the religious houses in Canterbury and two local hospitals. A small amount of jewelry was bequeathed to Alice, his servant, and an annuity of 6s. 8d. to his apprentice, John Pegeon, until he had finished his term. Mulling instructed his feoffees, William Benet, William Selowe and Thomas Prowde, to deliver seisin of his messuage in Canterbury to his widow, Elizabeth, but to sell his lands in the parish of Preston by Faversham and divide the proceeds between her, the prior of Christ Church for works at the cathedral, and the city’s poor. Mulling named three prominent local men, Selowe, Prowde and John Chamberlain as his executors, leaving them 20s. each for their trouble.
