One of at least three sons, Forster originated from Stanton Drew in north Somerset, where his younger brother Stephen was baptized. The latter pursued a successful career in London, while Thomas, the other brother, continued to reside in their home parish.
Forster also acquired interests in neighbouring Gloucestershire and, further afield, in Buckinghamshire. In April 1427 John Stafford, bishop of Bath and Wells, granted to him, his wife Joan and their sons, Richard and John, a messuage and lands at Serridge and Henfield within his manor of Pucklechurch in Gloucestershire, to hold for their lives for a rent of 40s. p.a. The grant, along with letters of acknowledgement from the dean and chapter of Wells and the prior and convent at Bath, was entered on the patent rolls in the following November.
At Bristol, Forster resided in Temple parish, although he also held property in other parts of the town. Perhaps his most significant acquisition there was that of holdings previously belonging to a fellow burgess, Thomas Blount†. Before he died in 1441, Blount sold the reversion of his dwelling house with shops and gardens in Temple Street, tenements in the same street and Tucker Street and a plot of land with a drying room in St. Thomas Street to Forster for £200. The reversion was to vest after the deaths of Blount and his second wife Margaret, although how long she survived her husband is unknown. Forster already owned shops in Temple Street when Blount made his will, which reveals that they lay next to the testator’s house.
The close relationship that Forster enjoyed with Thomas Blount might suggest that the two men were business colleagues. In earlier years, Forster had also had dealings with John Burton I*, one of the foremost Bristol staplers of the first half of the fifteenth century, although he fell out with Burton in the later 1420s, suing him in the court of common pleas. When the case came to pleadings in Michaelmas term 1428, he alleged that John owed him money, a debt arising from a bond made between them at London in August 1424. By means of this security, Burton had undertaken to pay him £244 (presumably in connexion with some business dealing) at Michaelmas 1425. While acknowledging that Burton had paid £184 of this sum, Forster asserted that £40 remained outstanding. Burton responded by seeking and obtaining licence to negotiate with his opponent out of court until Hilary term 1429. In the following term, he put in a plea that Forster had formally acquitted him of the £40, but the latter claimed that this release related to the payment of £184. Although the parties agreed to a trial, Burton subsequently obtained further licence to treat with Forster out of court, and it is likely that they resolved the dispute informally.
As one of the most prominent Bristol merchants of his day, Forster possessed considerable status in the town, making him a natural candidate for municipal office and a seat in Parliament. His career as an office-holder at Bristol followed a generally conventional pattern. Having served a term as one of the town’s bailiffs in 1429-30, he became sheriff in 1433, began the first of two terms as constable of the staple in the following year and the first of his three as mayor in 1436. As was quite usual, during each of his periods in the mayoralty he was concurrently mayor of the local staple; more unusually, his last couple of terms as mayor of the town, served after he had sat in his sole Parliament, were consecutive. During the same latter two terms, Henry VI twice visited and stayed at Bristol, first on 31 Aug. and 1 Sept. 1447 and secondly on 1-2 Aug. 1448.
It was following his first term as mayor of Bristol that Forster found himself facing demands from the Exchequer for various sums charged to the account for his period of office. He petitioned the Crown for relief, finally freeing himself from these demands in late 1444.
There is no evidence that Forster received any new municipal appointments after concluding his final term as mayor of Bristol in 1448, although he continued to attend meetings of the common council (as he had done since at least 1438), and he attested the election of the town’s MPs to the Parliament of 1449-50. He attended his last known council meeting in late August 1450 and drew up his will on the following 13 Oct.
The only surviving copy of the will, preserved in the records at Bristol, bears no date of probate, but Forster died within weeks of making it. He was certainly dead in the following December when his son and namesake sold property in the town’s High Street for 100 marks, for the deed recording the transaction referred to him as no longer alive.
It would appear that Forster’s widow did not long survive him, since the tenancy for their lives that she and her late husband had held in Stanton Drew had expired by April 1453. Forster’s son and namesake followed his father’s footsteps by serving a term as mayor of Bristol, in 1462-3, and trading as a merchant. Yet he also bore the style of ‘gentleman’ or ‘esquire’, and he was more a member of the Gloucestershire gentry than he was a burgess by the end of his life.
