Demmon History, Family Crest & Coats of Arms

Early Origins of the Demmon family

The surname Demmon was first found in Somerset where they held a family seat as Lords of the Manor. After the Battle of Hastings in 1066, William, Duke of Normandy, having prevailed over King Harold, granted most of Britain to his many victorious Barons. It was not uncommon to find a Baron, or a Bishop, with 60 or more Lordships scattered throughout the country. These he gave to his sons, nephews and other junior lines of his family and they became known as under-tenants. They adopted the Norman system of surnames which identified the under-tenant with his holdings so as to distinguish him from the senior stem of the family. After many rebellious wars between his Barons, Duke William, commissioned a census of all England to determine in 1086, settling once and for all, who held which land. He called the census the Domesday Book, [1] indicating that those holders registered would hold the land until the end of time. Hence, conjecturally, the surname is descended from the tenant of lands consisting of 55 Lordships, held by William de Moyon of Moion, near St.Lo in Normandy, who was at Hastings a great Norman Baron who was recorded in the Domesday Book census of 1086. Dunster Castle was his principal seat. He is buried in the priory in Bath. They became the Earls of Somerset and Dorset and the Barons of Okehampton.
