Beside his "mansion howse" at Shute, which was his principal residence, Sir William, as was usual, had a town house or hotel, in the parish of the Holy Trinity, Exeter. On 17 April, 1404, Bishop Stafford licensed John Govys rector of Holy Trinity, as the parish church was being rebuilt at the time, "ut in aula infra mansum domini Willelmi Bonevyle, militis, infra parochiam dicte ecclesie Sancte Trinitatis situatum, divina possis celebrare, ac per presbiteros ydoneos facere celebrari, necnon parochianis tuis quibuscumque Sacramenta et Sacramentalia conferre et ministrare valeas."
Of Sir William's sons, Richard the eldest died without issue before 1397. John the second son became his father's heir and successor.
Thomas Bonville, third son, married Cicely, daughter of Sir John Stretche of Sampford-Arundell, Somerset, who died 6 Aug., 1390, by his wife Katharine daughter of Sir John Beaumont, of Sherwill, North Devon. They had two sons, William who died 28 Aug., 1412, and John in 1426. Both were styled "of Merriot, Somerset," property that descended to them through their great-grandmother, and died without issue. He, Thomas, died about 1401, and his widow soon after married Sir William Cheney of Broke, Wilts, and died 18 Oct., 1430.[13]
William, the fourth son, died without issue; we hear nothing of him beyond his being a witness to his stepmother's will.
Katharine, the eldest daughter, married first Sir John Cobham, of Blackborough, Devon, by whom she had a daughter Elizabeth, married to Walter Charleton. Secondly she married John Wyke of Nynehead-Florey, Somerset, and thirdly Humphry Stafford of Grafton, Worcestershire. She died 1 Aug., 1416.
Elizabeth, second daughter, married about 1390, Sir Thomas Carew of Ottery-Mohun, who died 25 Jan., 1431. She died 8 Feb., 1450-1.
Sir William who was Sheriff of Devon 13 Richard II., 1400, died on 14 Feb., 1407-8, and was buried before the great Cross in the choir of Newenham Abbey Church. Beside him was afterward laid Alice his second wife. This was during the abbacy of Leonard Houndalre, who presided over the Community 1402-13.
He bequeaths by his will,—a very long document written in French,—and made
"on the Saturday next before the feast of the Assumption of our Lady, 1404, my body to be buried before the High Cross of the church of Newenham; to Alice my consort my mansion at Exeter for her life, all my books, vestments with other apparel belonging to my chapel, all kinds of necessaries belonging to my hall, chambers, pantry, buttery, kitchen and fish-pond, within my manor of Shute, and all other chattels on my manors of Wescombe, &c., &c., elsewhere, 100 marks in money, and the half of my silver vessels, &c.; 100 marks, to assist in making and repairing the bridges and roads that are weak and fallen within my lordships of Devon and Somerset; to alienate by mortmain 50 marks of land and of rent per year for a Maison Dieu in Combestreet at Exeter, for 12 poor men and women to be lodged there always, also 300 marks to the said Maison Dieu in honour of God, and to sustain the said house, and the aforesaid poor men and women, all my rents in Exeter, except my mansion;—to Dame Anne Bonville, nun of Wherwell, 10 marks, a hanapp (drinking cup) with silver cover, and my best hoppelond (great coat) with the fur. To William my son 200 marks to assist him in getting married; to Thomas son of John Bonville £20 in money; to John son of Thomas Bonville to assist him in getting married 100 marks. To my daughter Dame Katharine Cobham £20; to my daughter Dame Elizabeth Carew, £20. I devise that all my debts be duly and fully paid, and if any offences or extortions by me have been committed against any persons I will that they be restored to them, according to the greatness of the offence; 24 torches of wax, and 24 poor men be clothed the day of the interment of my body, and to other poor people coming on the day of my burial £10, that each who comes may have one penny; and that my mansion and my retinue be kept just as it is for one quarter of a year after my death. Appoints Alice my consort, and six clerks executors; Monsieur Thomas Brooke and John Strecch, surveyors; nothing to be done without the counsel and assent of the said surveyors."
There is also included a very large number of religious bequests to pray for the good estate of his soul, at various places, and legacies in money and kind, to the poor on his extensive estates.
