Dennisum History, Family Crest & Coats of Arms
The Dennisum 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 Dennisum family
The surname Dennisum 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.

Migration of the Dennisum family
The expense of the crossing to the North American colonies seemed small beside the difficulties of remaining in Scotland. It was a long and hard trip, but at its end lay the reward of freedom. Some Scots remained faithful to England and called themselves United Empire Loyalists, while others fought in the American War of Independence. Much of this lost Scottish heritage has been recovered in the last century through Clan societies and other patriotic Scottish organizations. A search of immigration and passenger lists revealed many important, early immigrants to North America bearing the name of Dennisum: Edward Denison, who settled in Virginia in 1623; Dannie Dennison, who was on record in New England in 1626; William Denison, his wife Margaret, and their three sons, who settled in Massachusetts in 1631.
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.
