John de Beauchamp, of Holt

The first baron to be formally created by letters patent under the Great Seal, which represents the Sovereign’s authority, was John Beauchamp de Holt, created Baron Kidderminster, by King Richard II in 1387. After about 1440 this became the normal method of creation of baronies.

JOHN de Beauchamp of Holt (-[1261/7 Jan 1269]). "Willelmus de Bello Campo" granted "totum manerium meum de la Holte…cum advocatione ecclesie eiusdem" to "Johanni filio meo", with default to "Waltero fratri suo minori", by charter dated to [1258/69][970]. "Willelmus de Bello Campo" granted "totum manerium meum in Schirrevelench et Chirchelench", except the part granted to "Bartholomeo de Sudleya et Johanne filie mee", to "Jacobo de Bello Campo fratri meo" (in default to "Johanni filio meo") by charter dated to [1261/69][971]. He is not named in his father’s testament dated 7 Jan 1268 so presumably died before that date.
