Early Origins of the Sea family

The surname Sea was first found in Kent where they held a family seat as Lords of the Manor of Seal in that shire. 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, Seal at the Domesday Book was held by Geoffrey de Rots as an undertenant from the Bishop of Bayeux. The holding was a fishery, consisting mainly of eels. Not surprisingly, the family Coat of Arms shows salmon swimming.

The British first settled the British West Indies around 1604. They made many attempts but failed in some to establish settlements on the Islands including Saint Lucia and Grenada. By 1627 they had managed to establish settlements on St. Kitts (St. Christopher) and Barbados, but by 1641 the Spanish had moved in and destroyed some of these including those at Providence Island. The British continued to expand the settlements including setting the First Federation in the British West Indies by 1674; some of the islands include Barbados, Bermuda, Cayman Island, Turks and Caicos, Jamaica and Belize then known as British Honduras. By the 1960's many of the islands became independent after the West Indies Federation which existed from 1958 to 1962 failed due to internal political conflicts. After this a number of Eastern Caribbean islands formed a free association. 6
