Mounsy is one of the thousands of new names that the Norman Conquest brought to England in 1066. The Mounsy 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. 1 His descendants occur in Sussex, but chiefly in Yorkshire and Lincoln.' " 2

"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. " 3

Early Origins of the Mounsy family

The surname Mounsy 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." 2

"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." 4

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. 5

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." 6

Mounsy Spelling Variations

Multitudes of spelling variations are a hallmark of Anglo Norman names. Most of these names evolved in the 11th and 12th century, in the time after the Normans introduced their own Norman French language into a country where Old and Middle English had no spelling rules and the languages of the court were French and Latin. To make matters worse, medieval scribes spelled words according to sound, so names frequently appeared differently in the various documents in which they were recorded. The name was spelled Mounsey, Mounsie, Mouncie, Mouncey, Mouncy, Muncey, Muncie, Mounceaus, Monceaux, Monceux, Monse and many more.

Early Notables of the Mounsy family

Migration of the Mounsy family

Because of this political and religious unrest within English society, many people decided to immigrate to the colonies. Families left for Ireland, North America, and Australia in enormous numbers, traveling at high cost in extremely inhospitable conditions. The New World in particular was a desirable destination, but the long voyage caused many to arrive sick and starving. Those who made it, though, were welcomed by opportunities far greater than they had known at home in England. Many of these families went on to make important contributions to the emerging nations of Canada and the United States. Analysis of immigration records indicates that some of the first North American immigrants bore the name Mounsy or a variant listed above: 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 Mounsy 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: Semper paratus
Motto Translation: Always prepared.
