Dennyss History, Family Crest & Coats of Arms
The Norman Conquest of England in 1066 brought much change, including many immigrants with new names. Among these were the ancestors of the Dennyss family, whose name comes from the medieval given name, Dennis, which comes from the Greek name Dionysios, which means a follower of the god Dionysius.
Early Origins of the Dennyss family
The surname Dennyss was first found in Lancashire. Conjecturally, the name came to us from Normandy, from the patron saint of France, St. Denis.  He was Bishop of Parisii (Paris), but was martyred in the Decian persecution of Christians, shortly after 250 AD. Apparently, after he was beheaded by a sword, he picked it up and walked ten kilometers (six miles), preaching a sermon the entire way. After the Norman Conquest of England at the Battle of Hastings in 1066 A.D., the family were granted extensive lands in Lancashire, Yorkshire, Northumberland, Devon and Cornwall.
The manor of Lesnewth in Cornwall belonged to the Dennis family in the reign of Charles I., "but it is now the property of E. J. Glynn, Esq. in whose family it has been vested nearly a century."

Dennyss Spelling Variations
Norman surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are largely due to the fact that the Old and Middle English languages lacked definite spelling rules. The introduction of Norman French to England, as well as the official court languages of Latin and French, also had pronounced influences on the spelling of surnames. Since medieval scribes and church officials recorded names as they sounded, rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings. The name has been spelled Dennis, Denis, Dennys, Dennyss, Denys, Denniss and many more.

Migration of the Dennyss family
Many English families emigrated to North American colonies in order to escape the political chaos in Britain at this time. Unfortunately, many English families made the trip to the New World under extremely harsh conditions. Overcrowding on the ships caused the majority of the immigrants to arrive diseased, famished, and destitute from the long journey across the stormy Atlantic. Despite these hardships, many of the families prospered and went on to make invaluable contributions to the development of the cultures of the United States and Canada. Early North American immigration records have revealed a number of people bearing the name Dennyss or a variant listed above: Thomas Dennis who settled in Boston in 1630. Edward Dennis settled there also about six years after. Danniel Dennis was banished to Barbados in 1635; Ann Dennis settled in Virginia in 1650.
