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.  
There is also evidence that some of the family originated in Normandy: "Richard, Fulco, Geoffry, Roger, Hugh, Matthew, Robert Daneis of Normandy, 1180-98 (Magni Rotuli Scaccarii Normanniae.)" 
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.
Early rolls listed the name as a forename and surname as was typical of the times. Early Lincolnshire records show: Dionisius de Chotum; Dionisia; and Denis de Sixlea in the Pipe Rolls of 1176. Other early entries include: Deonisia in the Curia Regis Rolls for Yorkshire in 1212; Denise in the Feet of Fines for Essex in 1321; Deonis in the Subsidy Rolls for Somerset in 1327; Dionis ate Brome in the Subsidy Rolls for Surrey in 1332; Denes; and Walter Denys in the Assize Rolls for Staffordshire in 1272. 
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." 
In Devon, the Abbey of Ashburton and the adjacent lands were granted to Sir Thomas Dennis, and descended in his family in the 13th century. 
"Dennis is an ancient name in Devonshire. In the reign of Henry II. an influential family of Le Deneis resided at Pancrasweek, in the hundred of Black Torrington, and from them sprang the knightly family of Dennis, of Blagdon and Manaton, and the families of Dennis of Holcomb - Buraell, Colliscombe, etc., in the 16th and 17th centuries (W. A. and W.). Dennis was a Bideford name in the 16th and 17th centuries, Anthony Dennis, of Orleigh, being mayor in the reign of James I., whilst Robert Dennis was a Bideford alderman somewhere about this period."

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.
