Mandevill History, Family Crest & Coats of Arms
The history of the Mandevill family name begins after the Norman Conquest of 1066. They lived in Mandeville, near Valognes, Cotentin, Normandy. In Mandeville, the Norman Mandevill 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 Mandevill family
The surname Mandevill 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.)

Migration of the Mandevill family to Ireland
Some of the Mandevill family moved to Ireland, but this topic is not covered in this excerpt.
To escape the political and religious chaos of this era, thousands of English families began to migrate to the New World in search of land and freedom from religious and political persecution. The passage was expensive and the ships were dark, crowded, and unsafe; however, those who made the voyage safely were encountered opportunities that were not available to them in their homeland. Many of the families that reached the New World at this time went on to make important contributions to the emerging nations of the United States and Canada. Research into various historical records has revealed some of first members of the Mandevill family to immigrate North America:
