The titles Baron Beauchamp and Viscount Beauchamp have been created several times throughout English and British history. There is an extant Viscountcy of Beauchamp, held by the Seymour family, Marquesses of Hertford.
Beauchamp family
The name Beauchamp (French "beautiful/fair field"), Latinised to de Bello Campo ("from the beautiful/fair field" or "from the fair battlefield"), is borne by one of the most ancient Anglo-Norman families which settled in England during the Norman Conquest of 1066.[5] The three main lines of the Beauchamp family were the Bedfordshire, the Somerset, and the Worchestershire branches.[6] The Bedfordshire branch died out in the male line after only two generations. The heir of the Somerset branch was the powerful Seymour family, whilst the Worcestershire branch achieved the greatest power and prominence as Earls of Warwick.

Viscount Beauchamp, first creation ("of Hache") (1536–1552)
The Seymour family inherited the capital manor of Hatch Beauchamp (anciently Hache) due to the marriage of Roger Seymour (d.c.1361) to Cecily Beauchamp (d.1393), the aunt and heiress of John IV de Beauchamp, 3rd Baron Beauchamp (1330-1361),[8]feudal baron of Hatch Beauchamp.
^Hugh de Beauchamp was the first Norman feudal baron of Bedford and held many manors in Bedfordshire as is recorded in the Domesday Book (Sanders, p.10) Since the Latin meaning is ambiguous, the surname may have been taken from the family's manor in Normandy or from some sort of military accomplishment.
