VCH Wiltshire and Berkshire record William, Richard, Jocelin and Walter de Rivers prior to 1100, and their descendants thereafter having property interests in Woodborough and Wootton Rivers close to Marlborough Castle (Wiltshire), and Beedon, Welford, and Woolley (Berkshire). Eventually they had property interests throughout the West country Presumably Jocelin, and Walter were related to Richard - the ancestor of the Earls of Devon. Has anyone amde a study of the Wiltshire and Berkshire de Rivers? Thank you Paul Bulkley
