Sebastian History, Family Crest & Coats of Arms
Early Origins of the Sebastian family
The surname Sebastian was first found in Cornwall 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,  indicating that those holders registered would hold the land until the end of time. Hence, conjecturally, the surname is descended from the tenant of the lands of St Columb Major who was recorded in the Domesday Book census of 1086. Sebastian is a masculine given name that is derived from the Latin name Sebastianus meaning "from Sebastia" and is also a surname derived from Saint Sebastian (died c. 288), an early Christian saint and martyr.

In England at this time, the uncertainty of the political and religious environment of the time caused many families to board ships for distant British colonies in the hopes of finding land and opportunity, and escaping persecution. The voyages were expensive, crowded, and difficult, though, and many arrived in North America sick, starved, and destitute. Those who did make it, however, were greeted with greater opportunities and freedoms that they could have experienced at home. Many of those families went on to make important contributions to the young nations in which they settled. Early immigration records have shown some of the first Sebastians to arrive on North American shores:

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.
