Demarse History, Family Crest & Coats of Arms
The name Demarse was originally "De La Mare, from the great fief of La Mare, near St. Opportune, in the comune of Autretot, Normandy; where their castle was built upon piles on the margin of the lake still called Grande-mare." 
One source claims the name was derived from the Old French word "marre," meaning "a ram."
Early Origins of the Demarse family
The surname Demarse was first found in Normandy where "Sire de la Mare is one of the Norman nobles enumerated by Wace at the battle of Hastings; and the family became very numerous both in Normandy and England. Sir William de la Mare, and his lands in the valley of La Mare, are mentioned in a charter of St. Louis, dated 1259; and as many as nine Sires de La Mare (almost all of them bearing different arms) are entered on the roll of "Gentilshommes de la Normandie" given in the Nobiliaire." 
The ancestor of the English families, Norman de La Mare, lived c. 1030 and Hugo de La Mare occurs in the Breton charter in 1070. This was one of his sons, of whom four went to England at the Conquest. 
William de Mare was an undertenant in Wiltshire and Herefordshire according to the Domesday Book of 1086.

Demarse Spelling Variations
French surnames were subject to numerous alterations in spelling because of the various cultural groups that inhabited specific regions. Eventually, each region possessed its own local dialect of the French language. The early development of the French language, however, was also influenced by other languages. For example, Old French was infused with Germanic words and sounds when barbarian tribes invaded and settled in France after the fall of the Roman Empire. Middle French also borrowed heavily from the Italian language during the Renaissance. As a result of these linguistic and cultural influences, the name Demarse is distinguished by a number of regional variations. The many spelling variations of the name include Marre, Marres, Mar, La Marre, La Mare, La Marres, La Mares, La Mar, Maur, Maure, Maures, Maurre, Maurres, More, Mores, Morre, Mars, Maurs, Moure, Mourre, Merre, Mer, Mere and many more.

Migration of the Demarse family
France was active as a cultural leader in the early 16th century. One particular area in which they lead was the exploration of the New World. The explorers, like Jacques Cartier in 1534, led the way to North America. Champlain, in 1608, made the first of twenty voyages to France to attract settlers and brought the first migrant in 1617. By 1675, there were 7000 French in Quebec, and the French Acadian presence in the Maritimes had reached 500. The French founded Lower Canada, thus becoming one of the two great founding nations of Canada. The family name Demarse has made many distinguished contributions in France and New France to the world of science, culture, religion, and education. Amongst the settlers in North America with this distinguished name Demarse were Alice Mare, aged 22; who settled in Barbados in 1635; Andrew Mare, who settled in Virginia in 1663; John Mare, who settled in Virginia in 1651; Mary Mare, who settled in Virginia in 1663.
