Bonnington obtained the freedom of Canterbury in July 1424 by his marriage to Christine, the daughter of John Cherche, a member of Canterbury’s elite who had served as jurat several times in the late fourteenth and early fifteenth centuries.
Having obtained the freedom of the city, Bonnington was soon involved in civic government. The following Michaelmas he was elected as one of the 12 jurats, in which position he served until Michaelmas 1426. It was not, however, until 1432 that he again served in civic government, when he was elected jurat for a third time. During this time he was active in affairs concerning the city and county: he witnessed the parliamentary election indenture for the county in 1432 and the following year he was elected, along with the experienced John Sheldwich*, to represent Canterbury in Parliament. He served for 112 days at Westminster, but donated 13s. 4d. to the city’s coffers to offset the charge of his wages for this unusually long Parliament.
The pinnacle of Bonnington’s career in city government came at Michaelmas 1435 when he was elected to the first of two consecutive terms as bailiff. During his first term he was embroiled in the city’s dispute with St. Augustine’s abbey over the manor of Langport. In May 1436 along with his fellow bailiff, William Osbourne, and John Lynde*, he led a group of citizens who invaded the close of the abbey, ostensibly to make a pilgrimage to St. Lawrence’s hospital.
Bonnington did not serve as mayor, bailiff or jurat during the 1440s but there is no explanation for his conspicuous absence from civic affairs. He certainly retained an interest in the city and in 1450 was assessed at an annual income of £20 for the subsidy, making him one of Canterbury’s wealthiest inhabitants.
Bonnington made his will on 10 Dec. 1463 and added a codicil concerning his lands on the following 20 Feb. He asked to be buried in St. Augustine’s abbey next to his late wife, Christine. Sums of money were left to his home parish of St. George and four other churches in Canterbury, and he ordered requiems to be sung in St. George’s and the abbey. He also provided for a mass to be sung in the abbey on the anniversary of his death for 52 years; and similar provisions were made for 20 years in memory of his parents, his late wife and her parents in St. Cross church, Westgate, and Littlebourne, Kent. Monetary bequests were also made to the city’s poor and the monks of St. Augustine’s, while his servants received items of clothing. Bonnington’s manor of Wolneston in Wingham and his other lands, debts and chattels were to be sold and the proceeds used to pay for the various masses and obits he had ordered and for gifts to local churches, hospitals and religious houses. The only lands that were to be disposed otherwise were a tenement in St. Gregory’s parish and lands in Chislet which were to be given to his grand-daughter and heiress, Joan (his son William having pre-deceased him at an unknown date) when she came of age. The date of Bonnington’s death is unknown but probate was granted on 20 Apr. 1464.
