Dennise History, Family Crest & Coats of Arms
The name Dennise arrived in England after the Norman Conquest of 1066. The name Dennise 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 Dennise family
The surname Dennise 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."

Dennise Spelling Variations
Endless spelling variations are a prevailing characteristic of Norman surnames. Old and Middle English lacked any definite spelling rules, and the introduction of Norman French added an unfamiliar ingredient to the English linguistic stew. French and Latin, the languages of the court, also influenced spellings. Finally, Medieval scribes generally spelled words according to how they sounded, so one person was often referred to by different spellings in different documents. The name has been spelled Dennis, Denis, Dennys, Dennyss, Denys, Denniss and many more.

Migration of the Dennise family to Ireland
Some of the Dennise family moved to Ireland, but this topic is not covered in this excerpt.
Migration of the Dennise family
To escape the political and religious persecution within England at the time, many English families left for the various British colonies abroad. The voyage was extremely difficult, though, and the cramped, dank ships caused many to arrive in the New World diseased and starving. But for those who made it, the trip was most often worth it. Many of the families who arrived went on to make valuable contributions to the emerging nations of Canada and the United States. An inquiry into the early roots of North American families reveals a number of immigrants bearing the name Dennise 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.
