Family
 Uncertain 1)Notes: History of Parliament identifies William's mother as Elizabeth, John's second wife. Her will describes William as her son. On the other hand, if William were a son of John's first wife Joan de Cherleton (daughter of John de Cherleton) then claims of kinship between Richard Beauchamp, Bishop of Salsibury, and Edward IV can actually be explained. While the latter solution is probably likelier, it has not been included here, for the moment. There are gaps in Richard's Beauchamps known ancestry which might explain the claims of kinship. Married/ Related to:  John de Beauchamp 1)Child: 1. William Beauchamp, Sir 1)Born ± 1355 Powick, Worcestershire, England Died ± 1421, approximately 66 years 1) Election: Elected on four occasions as MP for Worcester between 1407 and 1416 1) Notes: Through his political career William held a variety of roles including: Commissioner of Inquiry for various counties and topics Constable of Gloucester Castle (1392 - death) Sheriff of Worcester (Various dates after 1401) Chamberlain to Humphrey Duke of Gloucester | |||
