William Bruley, knight of the shire for Oxfordshire in 1395, outlived his wife and their son John, who had married Maud Quatremain, sister and coheiress of Richard Quatremain of Rycote. Before 1423, however, he had enfeoffed his granddaughter Joan and her husband John Danvers, of Epwell in Swalcliffe and later of Colthorpe in Banbury, with Waterstock manor. Danvers, who represented the county in three parliaments, and built up a large landed estate, was returned as lord in 1428 and appears to have died shortly after 1448. His widow Joan married as her second husband Sir Walter Mauntell of Nether Heyford and they presented to Waterstock church in 1467 and 1469. Much of John Danvers's property went to his sons by his first wife, but Thomas, his eldest son by Joan Bruley, succeeded to his mother's lands. He married twice, first a daughter of James Fiennes, Lord Saye and Sele, and secondly Sybil Fowler, member of a family with whom the Danvers family was already connected by marriage.[1]

Biography
John Danvers’s inheritance from his father, who died in or after 1409, was of small worth, comprising as it did not much more than the manor of Little Bourton in Cropredy and a few acres of land nearby. The manor of Epwell, which had been in the family since the 12th century, had fallen quite recently into the hands of William Wilcotes*, a leading Oxfordshire lawyer. However, through his mother he inherited the Brancaster property in Calthorpe and Wickham, and these holdings formed the basis for a notable expansion of territory, which proved to be Danvers’s principal achievement.2
[...]
Both of Danvers’s marriages proved advantageous: his first wife brought him land in Northamptonshire, and his second the manor of Waterstock, of which he had possession by 1423 under a settlement made by his wife’s grandfather William Bruley, the former shire knight.4

Danvers is last recorded in February 1449, as completing financial arrangements for the marriage of one of his daughters, but he died shortly afterwards, for the abbot of Eynsham later gave a receipt to his executors, regarding his farm of the abbey’s demesnes in Calthorpe, for the period beginning that Lady Day. His widow married Sir Walter Mauntell.7 Over the years Danvers had done much to promote the interests of his many children. Agnes, his daughter by his first wife, had been married to John Fray*, the chief baron of the Exchequer, and at least four of his sons — Robert Richard and their half-brothers Thomas and William — had been encouraged to enter the legal profession. Indeed, Robert, who had been recorder of London since 1442, was to be made a j.c.p. in 1450 , and William was to be promoted j.KB under Henry VII. The estates John Danvers had accumulated were divided between his sons.8
