Input: Question: In what city was Joan Arches' son born? Passage:By 1196 Hugh de Say, grandson of Hugh FitzOsbern, had transferred lordship of the manor of Souldern to his brother-in-law Thomas de Arderne. By 1279 the Ardernes were mesne lords, collecting rent from the de Lewknor family. By 1307 the de Lewknors had conveyed Souldern to the Abberbury family of Donnington, Berkshire. Sir Richard Abberbury, knight of the shire for Oxfordshire in 1373 and 1387, granted lands at Souldern to both Donnington Hospital and a house of Crutched Friars at Donnington. Sir Richard's nephew, another Richard Abberbury, inherited the remainder. The younger Richard seized the Crutched Friars' land at Souldern and granted it to William de la Pole, 1st Duke of Suffolk in 1448. The remainder of Richard's land at Souldern passed to his nephew Sir Richard Arches (d.1417), MP for Buckinghamshire in 1402, of Eythrope, Cranwell (both in the parish of Waddesdon) and Little Kimble, Buckinghamshire. Souldern was inherited by his daughter Joan Arches and her husband Sir John Dynham. When their son, John Dynham, 1st Baron Dynham, died in 1501, Souldern manor was divided into four parts which remained in separate hands until the 1590s.
