A friend asked me to answer this question: What is the last name of the person whose first wife, Constance de Bramshill, may have been the heiress of the Bramshill family?, using the article: The 1086 Domesday Book lists one of the two manors of Bromeselle (the Anglo-Norman spelling of Bromshyll) as held by Hugh de Port, whose family possessed it for nine generations. The last of the de Port line, William de Port (who had assumed the name St. John), died in 1346 without leaving a male heir. 
In the early 14th century, Sir John Foxley, Baron of the Exchequer, (c. 1270 – c. 1325), built and endowed a chapel in the village of Bramshill. His first wife, Constance de Bramshill, may have been the heiress of the Bramshill family. Their son, Thomas Foxley (c. 1305–60), became MP for Berkshire in 1325, and was appointed constable of Windsor Castle in 1328, soon after the accession of the 14-year-old Edward III. In 1347 he obtained a licence to build a manor house or small castle at Bramshill, which included a 2,500-acre (1,000 ha) wooded park. The house, built between 1351 and 1360, had thick walls, vaulted cellars, and an internal courtyard measuring 100 feet (30 m) by 80 feet (24 m). Based on the similarity of the surviving vaults under Bramshill House and those under what became the servants' hall and steward's room at Windsor Castle, it may have been a copy of William of Wykeham's work there.The estate remained in the hands of the Foxley family and their heirs, the Essex family, until 1499, when it was sold to Giles Daubeney, 1st Baron Daubeney. Giles's son Henry Daubeney (later Earl of Bridgewater) sold the property to Henry VIII, and in 1547 Edward VI granted the estate to William Paulet, whose heirs sold it in 1600 to Sir Stephen Thornhurst of Agnes Court, Kent., what would be the answer ?



Constance de Bramshill
