Jervass History, Family Crest & Coats of Arms
The ancestors of the Jervass family first reached the shores of England in the wave of migration after the Norman Conquest of 1066. Their name is derived from the Norman personal name Gervase. The surname Gervais indicates that the bearer is a descendant of someone named Gervase. 
Gervase of Canterbury (Gervasius Dorobornensis) (fl. 1188), was an English "chronicler, was born, apparently of a Kentish family, about 1141. As he had a brother Thomas in his monastery, who is conjectured to be identical with one Thomas of Maidstone, we have a possible clue to his birthplace; but the information is too imperfect to warrant more than an hypothesis. Gervase became a monk of Christ Church, Canterbury, on the first Saturday in Lent, 16 Feb. 1163." 
Gervase of Chichester (fl. 1170), was an English commentator, one of the band of learned young men who gathered round Thomas, Archbishop of Canterbury and Gervase of Tilbury (fl. 1211), was author of the ‘Otia Imperialia,’ was no doubt a native of Tilbury in Essex, though he appears to have been brought up in Rome, and to have spent some years of his early life in Italy. 
Early Origins of the Jervass family
The surname Jervass was first found in Cornwall. The Gervais surname also spelled Jarvis, Gervays and Gervis, was first found in Mobonnaiss and Vallee, in Brettagne, the ancient name for Brittany, and arrived in England with William, Duke of Normandy, in 1066. 
The first records of the family were listed in their Latin form, as in John filius Gervacii, Cambridgeshire; William filius Gervasii, Huntingdonshire; and Stephen Gervcis, Cambridgeshire. All were listed in the Hundredorum Rolls of 1273.

Jervass Spelling Variations
Norman surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are largely due to the fact that the Old and Middle English languages lacked definite spelling rules. The introduction of Norman French to England, as well as the official court languages of Latin and French, also had pronounced influences on the spelling of surnames. Since medieval 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. The name has been spelled Gervais, Gervays, Gervis, Jarvis, Jervis and others.

Migration of the Jervass family
Many English families emigrated to North American colonies in order to escape the political chaos in Britain at this time. Unfortunately, many English families made the trip to the New World under extremely harsh conditions. Overcrowding on the ships caused the majority of the immigrants to arrive diseased, famished, and destitute from the long journey across the stormy Atlantic. Despite these hardships, many of the families prospered and went on to make invaluable contributions to the development of the cultures of the United States and Canada. Early North American immigration records have revealed a number of people bearing the name Jervass or a variant listed above: John Jarvis who landed in Salem Massachusetts in 1630 and Thomas Gervais who settled in Maryland in 1634; Robert Jervis settled in Virginia in 1660; Richard Jervis settled in Maryland in 1720.
