Gusterson History, Family Crest & Coats of Arms
The ancient Anglo-Saxon surname Gusterson came from the baptismal name which means Custance. Alternatively the name could have been a local name for someone from Coutance, a location name in Normandy. 
Early Origins of the Gusterson family
The surname Gusterson was first found in the Hundredorum Rolls of 1273 as both a forename and surname: Constance, or Custance de Byerne, Nottinghamshire; John Custaunce, Cambridgeshire; Henry filius Custance, Cambridgeshire; and Custance Burnard, Cambridgeshire.
Later the Yorkshire Poll Tax Rolls of 1379 continued this tradition with: Custance de Bergh; and Adam Custanson. "The last two instances entered together are probably mother and son. "

Gusterson Spelling Variations
Sound was what guided spelling in the essentially pre-literate Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Also, before the advent of the printing press and the first dictionaries, the English language was not standardized. Therefore, spelling variations were common, even among the names of the most literate people. Known variations of the Gusterson family name include Custerson, Custer, Custance, Constance, Custeson and others.

For political, religious, and economic reasons, thousands of English families boarded ships for Ireland, the Canadas, the America colonies, and many of smaller tropical colonies in the hope of finding better lives abroad.

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: Appetitus rationi pareat
Motto Translation: Let your desires obey your reason.
