The Greville family is believed to be of Norman or Flemish origin and had settled in Chipping Campden by 1276. Leland (d.1552) stated: ""Sum hold opinion that the Grevilles cam originally in at the Conquest"", but although the name appears Norman in style, surviving records do not mention the family before the 13th century. The name is similar to that of Grenville of Bideford in Devon and of Stowe, Kilkhampton in Cornwall, later Earls of Bath, which is known to have had common ancestry with the Norman nobleman Richard de Grenville (died after 1142), one of the Twelve Knights of Glamorgan.
