Byrun History, Family Crest & Coats of Arms
The name Byrun reached England in the great wave of migration following the Norman Conquest of 1066. The Byrun family lived in Lancashire, Nottinghamshire and Yorkshire. As a Norman name, they claim descent from Beuron, near Mantes, Normandy, where the family lived prior to coming to England with the Norman invasion. 
The name literally means "descendant of Byron (from the cottage); one who came from Byram (tumulus or cowshed), in Yorkshire." 
Early Origins of the Byrun family
The surname Byrun was first found in Yorkshire where "the poet's ancestors were of unquestioned Norman origin. Ernisius (Erneis) de Burun held 32 lordships in Yorkshire, and Ralph de Burun, 13 in Nottinghamshire and Derbyshire, at the compilation of Domesday [Book]."  
At about the same time, "Ralph de Biron held a barony in Notts and Derby, and had his castle in the latter county. How they were related to each other is not positively known, but they were probably brothers ; and it is from Ralph that the Barons Byron descend. His posterity remained seated at Horestan Castle for three generations, till Robert de Biron married the heiress of Clayton, and they removed (moved) into Lancashire." 
"The Byrons belong to a very ancient and distinguished family of Nottingham, ennobled by James I.; and, as we also learn from Deering, Sir John Byron was constable of Nottingham castle in the reign of Henry VIII. Byron is still a Nottingham name." 
Delving more into Nottinghamshire records, we found at Hucknall-Torkard, "the church is an ancient edifice, containing several monuments to different members of the Byron family, lords of Newstead Abbey, about two miles distant. Here lie the remains of the late celebrated poet, who was interred here, on the 16th of July, 1824, in the family vault: in the chancel is a neat mural monument, with an appropriate inscription. There is also a monument to his ancestor, Richard, Lord Byron, who, with seven brothers, faithfully served Charles I. during the civil war, and sustained great losses and hardships on account of loyalty to that monarch." 
Back in Yorkshire, "this surname is derived from a geographical locality. 'of Byram,' a township in the parish of Brotherton, Yorkshire, formerly Byrom." 
The Hundredorum Rolls of 1273 included: Roger de Birun, Yorkshire; Ralph de Birun, Lincolnshire; and Hugh de Byron, Nottinghamshire, while the Yorkshire Poll Tax Rolls of 1397 listed Johannes de Byrom; Elena de Byron (Byrom); Roger de Birne (Monk Fryston); and Thomas de Byrne (Selby.) 
The family could have claimed decent from "the parish of Winwick, Lancashire. All the Lancashire Byroms hail from this spot. "  Again in Lancashire, but at Woolstone, with Martinscroft, a township, in the parish and union of Warrington, hundred of West Derby, we found: "in the 20th of Edward I., John Byrun claimed free warren here in right of his wife Alesia, heiress of Robert Banastre."

Byrun 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 Byrun family name include Biron, Byron and others.
Early Notables of the Byrun family (pre 1700)

Migration of the Byrun 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 Byrun family to immigrate North America: Elizabeth Byron who settled in Barbados in 1664; Sunnell Byron settled in Virginia in 1663; William Byron settled in Virginia in 1776.
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: Crede Byron
Motto Translation: Trust Byron.
