Jocelins History, Family Crest & Coats of Arms
While surnames were well-known during the English medieval period, Cornish People originally used only a single name. The way in which hereditary surnames came into common use is interesting. Under the Feudal System of government, surnames evolved and they often reflected life on the manor and in the field. Patronymic surnames were derived from given names and were the predominant type of surname among the Celtic peoples of Britain. However, the people of Cornwall provide a surprising exception to this rule, and patronymic surnames are less common among them than other people of Celtic stock, such as their Welsh neighbors. This type of surname blended perfectly with the prevailing Feudal System. One feature that is occasionally found in Cornish surnames of this type is the suffix -oe or -ow; this is derived from the Cornish plural suffix -ow. is a patronymic surname that came from the Germanic personal name Jocelyn, meaning Goth.
Gocelin or Gotselin (fl. 1099), was an early English "biographer, is said to have been born at or near Terouanne. He was originally a monk in the monastery of St. Bertin, and was brought over to England by Hermann, Bishop of Salisbury (1045-1077), possibly in 1058. He himself states that he accompanied Hermann to Rome shortly before the great council of Rheims (3 Oct. 1049), and as Hermann returned to England soon after Godwin's death."

Jocelins Spelling Variations
Cornish surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are due to the fact that the Old and Middle English languages lacked definite spelling rules. The official court languages, which were Latin and French, were also influential on the spelling of a surname. Since the spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England, which accelerated and accentuated the alterations to the spelling of various surnames. Lastly, spelling variations often resulted from the linguistic differences between the people of Cornwall and the rest of England. The Cornish spoke a unique Brythonic Celtic language which was first recorded in written documents during the 10th century. However, they became increasingly Anglicized, and Cornish became extinct as a spoken language in 1777, although it has been revived by Cornish patriots in the modern era. The name has been spelled Jocelyn, Gocelyn, Josselyn, Josselyne and others.

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: Faire mon devoir
Motto Translation: To do my duty.
