William was a younger son of Vincent Fynch, who having represented the Cinque Port of Winchelsea in three Parliaments at the turn of the century, had emerged as a leading member of the gentry of east Sussex, and officiated as escheator and sheriff in the county. Vincent’s manors of Icklesham and Netherfield near Battle were assessed for the purposes of taxation at £30 a year, but it seems likely that his total income well exceeded this amount. When he died, at an unknown date in or shortly after 1415, not all of this passed to his elder son and namesake; some of his landed holdings had already been settled on our MP.
After Vincent died, in about 1430, William took over the family seat at Netherfield, and a year or so later his kinsman Herbert Fynch conveyed to him all his property in Battle. By the time he entered the Commons our MP also occupied the town house at Battle that traditionally went with the local manor of Beche. A contemporary rental notes that the holder of this burgage was obliged to serve the abbot of Battle as his ceremonial cup-bearer, so Fynch would have been responsible for carrying the abbot’s cup to Parliament, and attending on him at Westminster when required.
Not only was Fynch well endowed with land, he could also boast important connexions among the gentry of east Sussex. Probably related by marriage to John Ashburnham†, the former shire knight, on the day after Ashburnham’s death, on 23 Nov. 1417, he allegedly assisted the deceased’s son to enter the manor of Scotney by force, and make off with boxes of title deeds and goods worth £40, thus provoking the anger of John’s executors.
Albeit members of the gentry, the Fynches always maintained their close connexion with Winchelsea, where their family had first emerged as successful merchants. William witnessed important transactions completed there in 1432, finally fulfilling the testamentary provisions of John Salerne† (d.1410),
On 10 Oct. 1440 Fynch made an enfeoffment of his lands in Sussex, Kent and the liberty of the Cinque Ports, naming among the feoffees the then sheriff of Kent Gervase Clifton* (who was married to his sister Isabel), the lawyer William Sydney* and his kinsman Richard Lewknor*. When he came to make his will, on 10 Sept. 1443, he instructed them to settle all of his real estate on his widow Agnes for term of her life, and stipulated that provided she remained single their children should be left under her governance; Agnes was to take responsibility for educating them until they reached the age of 20. Then, his eldest son, John, was to receive 20 marks, and the younger ones (William, Henry and Vincent), annuities of ten marks each, while 200 marks should be set aside for the marriage of his daughter, Isabel. If Isabel died unmarried, her portion was to be divided so that one Joan atte Rede would have ten marks and the balance would be split between the testator’s unmarried sisters, Denise and Parnel Fynch. If his widow remarried she was to be assured of an income of 100 marks p.a. for the rest of her life. After her death the bulk of the Fynch estates, including the manor of Netherfield, were to pass to John, while the younger boys were assured of specified lands to hold in fee simple.
