Dennisson History, Family Crest & Coats of Arms
The Dennisson surname is a patronymic, created from the personal name Dennis; thus the name originally meant "son of Dennis." Dennis comes ultimately from the Latin Dionysius.
Early Origins of the Dennisson family
The surname Dennisson was first found in Yorkshire where the first record of the name was found in 1212. Richard Dionys of Yorkshire, was listed in the Yorkshire Poll Tax of 1379. 
Some were found at the chapelry of Speeton in the East Riding of Yorkshire. "This township, which belongs to W. J. Denison, Esq., comprises about 1820 acres of land, and commands a beautiful view of the shore from Scarborough to Flamborough Head: the village is situated on an eminence north-east of the road from Bridlington to Scarborough." 
However, there is much dispute over the origin of the name. Some claim the name was derived from the Scottish Dennistouns.  Yet the author admits that name was also found in Norfolk and Suffolk in early times too. Thomas Denison, one of the Society of Merchant Adventurers, was buried in Leeds parish church in 1708.

The freedom of the North American colonies was enticing, and many Scots left to make the great crossing. It was a long and hard journey, but its reward was a place where there was more land than people and tolerance was far easier to come by. Many of these people came together to fight for a new nation in the American War of Independence, while others remained loyal to the old order as United Empire Loyalists. The ancestors of Scots in North America have recovered much of this heritage in the 20th century through Clan societies and other such organizations. A search of immigration and passenger lists revealed many important and early immigrants to North America bearing the name of Dennisson:

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Adversa virtute repello
Motto Translation: I repel adversity by virtue.
