Giss History, Family Crest & Coats of Arms
The name Giss reached English shores for the first time with the ancestors of the Giss family as they migrated following the Norman Conquest of 1066. The Giss family lived in Gloucestershire. The name, however, refers to the district of Guise in France, where the family was resident prior to the Norman Conquest of England in 1066.  Aspley Guise is a village and civil parish located in central Bedfordshire.
"Guy of Warwick, hero of romance, is almost wholly a creature of fiction. Dugdale and other historians of Warwickshire literally accepted as historical the series of legends respecting him, to which literary shape seems to have been first given by an Anglo-Norman poet of the twelfth century." 
Early Origins of the Giss family
The surname Giss was first found in Gloucestershire where they held a family seat as Lords of the Manor of Elmore in that shire, and were descended from Sir William Gyse who attended Duke William in his Conquest of England at the Battle of Hastings in 1066 A.D.
It is believed that Sir William first held the manor of Highnam from Gloucester Abbey but by the later marriage of Anselm Gyse to Magotta de Burgh (Burke,) daughter of the Earl of Kent, he acquired the Lordship of both Highnam and Elmore in Gloucestershire.
Some of the first records in various early rolls include: Robert de Guuis who was listed in the Pipe Rolls for Gloucestershire in 1207; and John de Gyse in the Pipe Rolls for Berskhire in 1230. 
The Hundredorum Rolls of 1273 list Anselm de Gyse in Huntingdonshire. John de Gyse was listed in Bedfordshire, 20 Edward I (during the twentieth year of King Edward I's reign) and the same source notes that William de Gyse was listed in Norfolk at that time.

Giss Spelling Variations
Anglo-Norman names tend to be marked by an enormous number of spelling variations. This is largely due to the fact that Old and Middle English lacked any spelling rules when Norman French was introduced in the 11th century. The languages of the English courts at that time were French and Latin. These various languages mixed quite freely in the evolving social milieu. The final element of this mix is that medieval scribes spelled words according to their sounds rather than any definite rules, so a name was often spelled in as many different ways as the number of documents it appeared in. The name was spelled Gyse, Guise, Guys, Guy, Gysse, Gyss, Gise, Gwyse and many more.

Migration of the Giss family to Ireland
Some of the Giss family moved to Ireland, but this topic is not covered in this excerpt.
Because of the political and religious discontent in England, families began to migrate abroad in enormous numbers. Faced with persecution and starvation at home, the open frontiers and generally less oppressive social environment of the New World seemed tantalizing indeed to many English people. The trip was difficult, and not all made it unscathed, but many of those who did get to Canada and the United States made important contributions to the young nations in which they settled. Some of the first North American settlers with Giss name or one of its variants:

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.
