Cavendish is one of the names that was brought to England in the wave of migration following the Norman Conquest of 1066. The Cavendish family lived in Suffolk where Gernon de Montfichet was granted the lands of Cavendish by Duke William of Normandy. 1

"The descent of the Cavendish family from Gernon has been disputed, but (as I intend to show) without reason. The Gernons were a branch of the Barons of Montfichet, Montfiquet, or Montfiket in Normandy, so named after their Scandinavian ancestor. The castle of Montfichet long remained, as well as the Church of St. Catherine in the castle, a foundation of this family. About 1050 Robert, surnamed Guernon (moustache), Baron of Montfichet, witnessed a charter of Duke William (Gall. Christ. xi. Instr. 229). He had issue, 1, William de Montfichet, who d. s. p., when the barony devolved on Wil­liam, the son of his brother; 2, Robert Guernon or Gernon, who held a great barony in Essex, &c., 1086. From his elder son William de Montfichet descended the Barons of that name, whose seats were at Stanstead Montfichet, Essex, and Montfichet Tower, London, of which city the Montfichets were hereditary standard-bearers or military chiefs in time of war. The younger branches retained the name of Gernon. Alured Gernon, brother of William de Montfichet, had estates in Essex and Middlesex 1130 (Rot. Pip.). Matthew, his son, 1135 witnessed a charter of William Montfichet (Mon. i. 803). Ralph, his son, 1165, held a fief from Montfichet in Essex, and was granted Bakewell, Derbyshire, by Richard I. (Testa de Neville). He had Ralph G., founder of Lees Priory, Essex, father of William G., who had two sons : l, Ralph, ancestor of a line of Gernon frequently mentioned in Essex, Suffolk, and Derby, and which long continued; 2, Geoffry. Geoffry, surnamed de Cavendish from his residence at Cavendish, Suffolk, appears in 1302 as bailsman with Walter de Cavendish, his son, for certain citizens of London who had been charged with the unlawful possession of some crown jewels." 2

Early Origins of the Cavendish family

The surname Cavendish was first found in Suffolk, when Gernon de Montfichet was granted the lands of Cavendish by Duke William of Normandy, his liege lord, for distinguished assistance at the Battle of Hastings in 1066 A.D. The Montfichets from Montfiquet, Calvados, in Normandy, sired the family of Cavendish, Bacon, Fitchet, and Montfitchet.

The family trace their lineage back to "Sir John Canvendish, who in the reign of Edward III was Chief Justice of the King's Bench. It was John, a younger son of the Judge, who killed Wat Tyler, and from him the family are descended." 3

"Chief Justice Cavendish had a tragic end. He was beheaded in the market place of Bury, during an insurrection in 1382." 4

United States Cavendish migration to the United States +

In England at this time, the uncertainty of the political and religious environment of the time caused many families to board ships for distant British colonies in the hopes of finding land and opportunity, and escaping persecution. The voyages were expensive, crowded, and difficult, though, and many arrived in North America sick, starved, and destitute. Those who did make it, however, were greeted with greater opportunities and freedoms that they could have experienced at home. Many of those families went on to make important contributions to the young nations in which they settled. Early immigration records have shown some of the first Cavendishs to arrive on North American shores:

The Cavendish Motto +

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: Cavendo tutus
Motto Translation: Safe by being cautious.
