Monceau History, Family Crest & Coats of Arms
Monceau is one of the names that was brought to England in the wave of migration following the Norman Conquest of 1066. The Monceau family lived in Monceaux, Normandy. "The 'Sire de Monceals' of the Roman de Ron. He 'descended from the ancient lords of Maers and Monceaux, Counts of Nevers. Landric IV. became Count of Nevers c. 990 by marriage, and had a younger son Landric of Nevers, Baron of Monceaux, grandfather of William de Monceaux, who is mentioned by Wace in 1066. He appears as William de Moncellis in the Eastern Domesday, and as William de Nevers in Norfolk 1086.  His descendants occur in Sussex, but chiefly in Yorkshire and Lincoln.' " 
"There are several communes of this name in Normandy; but Monceaux, near Bayeux, is probably the one meant. This name is frequently to be found in the earlier muniments of Battle Abbey; for a branch of the family, soon after the Conquest, settled at Bodiham, in its immediate neighbourhood. Part of his estate there was granted by William de Monceaux to the Abbey, at some date previous to 1200. " 
Early Origins of the Monceau family
The surname Monceau was first found in Sussex where they held a family seat as lords of the manor of Herstmonceux. They were descended from the ancient Lords of Maers and Monceaux, Counts of Nevers in Normandy. They were granted lands in Sussex and those branches, retaining the name Monceaux became the Lords of Monson, the Viscounts Castlemaine, and the Lords Sondes.
The first record of the family was "Drogo de Moncy [who] came to England 1066, and was in Palestine 1096. Drogo de Moncy, his son, had a pardon in Sussex 1130. In 1299 Walter de Moncy was summoned to Parliament as a baron." 
"The Moncys held Thornton of the Percy fee in Yorkshire. 'Walter de Muncy, 28 Edward I. had a charter for free-warren in his demesne lands at Thornton juxta Skipton, Everby, and Kelbroke in the co. of York. From the frequency of his name in the writs of summons of his time, he must have been a person of great eminence. In 29 Edward I, he was one of those barons Avho, in the parliament at Lincoln, subscribed that memorable letter which was addressed to the Pope,asserting the King's supremacy over the realm of Scotland; on which occasion he was denominated Dominus de Thornton." 
Another branch moved north into Cumberland soon after the Conquest: Hammond Monceaux was Sheriff of Cumberland in 1290, and it is there that the Mounsey branch is thought to have arisen.
In Lincolnshire, Edonea de Munchaus was listed as a Knights Templar in 1185 and a few years later, William Munci was listed in the Feet of Fines for Gloucestershire in 1198. 
Later, Walter de Muncy, 1st Baron Muncy (d. c. 1309), was summoned to Parliament and was accordingly granted a peerage on 6 February 1299. This gentleman may be the same person referenced at Thornton in the West Riding of Yorkshire in early times. "This place in the reign of Edward I. belonged to Walter de Muncey, who obtained from that monarch the grant of a weekly market, and a fair on the festival of St. Thomas the Martyr and four following days."

Monceau Spelling Variations
Before the advent of the printing press and the first dictionaries, the English language was not standardized. Sound was what guided spelling in the Middle Ages, so one person's name was often recorded under several variations during a single lifetime. Spelling variations were common, even among the names of the most literate people. Known variations of the Monceau family name include Mounsey, Mounsie, Mouncie, Mouncey, Mouncy, Muncey, Muncie, Mounceaus, Monceaux, Monceux, Monse and many more.
Early Notables of the Monceau family (pre 1700)
Outstanding amongst the family at this time was Messenger Monsey (1693-1788), physician, born in 1693, was eldest son of Robert Monsey, some time rector of Bawdeswell, Norfolk, but ejected as a nonjuror, and his wife Mary, daughter of the Rev. Roger Clopton. (The family of Monsey or Mounsey is supposed to be derived from the Norman house of De Monceaux.) Monsey was educated at home, and afterwards at Pembroke College, Cambridge, where he graduated B.A. in 1714.

Migration of the Monceau family
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 Monceau family to immigrate North America: Margaret Mouncey, who settled in Pennsylvania in 1697; Jean Mouncy who settled in Charles Town South Carolina in 1772; Joseph Monsey, who arrived in Ontario in 1871.
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: Semper paratus
Motto Translation: Always prepared.
