Early Origins of the Jenness family

The surname Jenness was first found in Cambridgeshire 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 the lands, Etienne de Gennes, a Norman of Anjou, from whom was descended Ettiennes de Gennes, Lord of Le Motte de Geenes in 1144 and who was recorded in the Domesday Book census of 1086.

United States Jenness migration to the United States +

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 Jennesss to arrive on North American shores:
