Mandevil History, Family Crest & Coats of Arms
The history of the Mandevil family name begins after the Norman Conquest of 1066. They lived in Mandeville, near Valognes, Cotentin, Normandy. In Mandeville, the Norman Mandevil family were nobles who possessed a castle and vast estates. 
"Upon the first arrival in England of the Conqueror, there was amongst his companions a famous soldier, called Geffray de Magnavil, so designated from the town of Magnavil in the Duchy of Normandy, who obtained as his share in the spoil of conquest, divers fair and wide spreading domains in the counties of Berks, Suffolk, Middlesex, Surrey, Oxford, Cambridge, Harts, Northampton, Warwick, and Essex. The grandson of this richly gifted noble, another Geoffrey de Mandeville, was advanced by King Stephen to the Earldom of Essex." 
Early Origins of the Mandevil family
The surname Mandevil was first found in Wiltshire where they were anciently granted lands by William Duke of Normandy for their assistance at the Battle of Hastings in 1066 A.D. Geoffrey (Goisfrid) de Mandeville (c.1100) was an important Domesday tenant-in-chief; he was granted large estates in Essex, and in ten other shires by William, and was Constable of the Tower of London. 
They were granted no less than 118 Lordships after the Conquest. William's descendent Geoffrey de Mandeville (d. 1144,) was created the 1st Earl of Essex, a title which became extinct in the 12th century after the death of the 3rd Earl.
The chief seat of the Mandevilles was at Walden in Essex, but many junior lines abounded. "Jehan de Mandeville", translated as "Sir John Mandeville", was noted as the compiler of a singular book of supposed travels, written in Anglo-Norman French, published between 1357 and 1371. They were Lords of the Manor of Earl's Stoke, in Wiltshire and also were granted lands in Devon.
Early rolls proved their widespread influence. Ernulf de Mandeuill was recorded in the Pipe Rolls for Wiltshire in 1158 and later, William de Manevell was found in Berkshire in the Curia Regis Rolls for 1210. Willaim de Manewell was registered in the Subsidy Rolls for Sussex in 1296. 
The Hundredorum Rolls of 1273 included: Nigel de Manderville, Berkshire; and Ernald de Maundeville, Suffolk. 
The Testa de Nevill, sive Liber Feodorum, temp. Henry III-Edward I listed Walter de Maundevill, Kent, 20 Edward I (during the twentieth year of King Edward I's reign.)

Mandevil Spelling Variations
Anglo-Norman names are characterized by a multitude of spelling variations. When the Normans became the ruling people of England in the 11th century, they introduced a new language into a society where the main languages of Old and later Middle English had no definite spelling rules. These languages were more often spoken than written, so they blended freely with one another. Contributing to this mixing of tongues was the fact that medieval scribes spelled words according to sound, ensuring that a person's name would appear differently in nearly every document in which it was recorded. The name has been spelled Mansville, Manvell, Mandeville, Magneville, Magnevilla, Manville, Mannevill, Manneville, Mandevile, Mansvile, Mansville, Mandevill, Manvill, Mansvill, Mansvil, Mandevil, Mandervil, Mandervill, Manderville, Mandavile, Mandavil, Mandavill, Mandaville, Mandavall, Mandavalle, Mandaval, Mandvill, Mandville, Mandvil and many more.

Migration of the Mandevil family
For many English families, the political and religious disarray that plagued their homeland made the frontiers of the New World an attractive prospect. Thousands migrated, aboard cramped disease-ridden ships. They arrived sick, poor, and hungry, but were welcomed in many cases with far greater opportunity than at home in England. Many of these hardy settlers went on to make important contributions to the emerging nations in which they landed. Among early immigrants bearing the name Mandevil or a variant listed above were: Gillis Mandeville, who settled in New York in 1659; Miss Mandeville settled in Barbados in 1774; Mary Mandeville settled in Maryland in 1738. In Newfoundland, Canada, Patrick Mandavile from Clonmell, Tipperary, was married in St. John's in 1805.
