Mowrer History, Family Crest & Coats of Arms
The name Mowrer was carried to England in the enormous movement of people that followed the Norman Conquest of 1066. The Mowrer family lived in Northumberland. The name, however, is a reference to the family's place of residence prior to the Norman Conquest of England in 1066, Montbrai, in La Manche, Normandy. 
However, another source claims the family claim descent from "the ancient barony of Mowbray, called by Odericus Vitalis Molbraium, [which] was identical with the village of Monbrai, in the canton or Perci, an arrondissement of St. Lo in Normandy." 
Early Origins of the Mowrer family
The surname Mowrer was first found in Northumberland where Geoffrey de Montbray (d. 1093,) Bishop of Coutances was a warrior, administrator and close assistant of William the Conqueror.
After the death of William, Geoffrey settled in Bristol, (as listed in the Domesday Book) where he built a strong castle but frequently feuded with William II." A strong castle was erected [at Thirsk in the North Riding of Yorkshire] about 979 by the family of Mowbray, where Roger de Mowbray in the time of Henry II., having become a confederate of the King of Scotland, erected his standard against his lawful sovereign: upon the suppression of the revolt, this fortress, with many others, was entirely demolished by order of the king." 
The same Roger de Mowbray also held Bambrough Castle in Northumberland. "After the Norman Conquest it was held by Robert de Mowbray, on whose insurrection against William Rufus it was besieged, and, after an obstinate defence, surrendered to that monarch, who threatened, unless it were given up, to put out the eyes of Mowbray, who had been taken prisoner." 
The markettown and parish of Kirby-Malzeard in the West Riding of Yorkshire was another ancient family seat. "This place was the property of the Mowbray family, afterwards dukes of Norfolk, whose castle here was demolished in the reign of Henry II., and one of whom, John de Mowbray, obtained for the inhabitants in the reign of Edward I. a charter for a weekly market and two annual fairs." 
"The Mowbrays used the mulBerry as their rebus. Thomas Duke of Norfolk, at his famous duel with the Duke of Hereford at Coventry, rode a 'horse barded with crimson velvet embroydered with Lions of silver and mulberry trees.' "

Mowrer Spelling Variations
Endless spelling variations are a prevailing characteristic of Norman surnames. Old and Middle English lacked any definite spelling rules, and the introduction of Norman French added an unfamiliar ingredient to the English linguistic stew. French and Latin, the languages of the court, also influenced spellings. Finally, Medieval scribes generally spelled words according to how they sounded, so one person was often referred to by different spellings in different documents. The name has been spelled Mowbray, Moubray, Mowbrey, Moubrey and others.

To escape the political and religious persecution within England at the time, many English families left for the various British colonies abroad. The voyage was extremely difficult, though, and the cramped, dank ships caused many to arrive in the New World diseased and starving. But for those who made it, the trip was most often worth it. Many of the families who arrived went on to make valuable contributions to the emerging nations of Canada and the United States.
