Origin
[edit]
A furore Normannorum, libera nos, Domine!
THE KING OF AMIGNY ... It is therefore to the seventh century that we would have to go back and delve into the furious hordes of those indomitable Norsemen, whose origins we have just outlined, to find there, in France, the mother stock of those LE ROYs we are discussing ...
— Du Cluzel de Remaurin, Knight
Normandy
[edit]Written interchangeably in records as: Roi, Le Roi, De Roy, and Le Roy, the surname Leroi originated from the Normans, the descendants of Norse Vikings who settled in Amigny, a commune in Manche, Normandy in the 10th century.[1][2][3]
Le Roi derived from the Old Northern French roi, roy (Old French pronunciation: [rɔi̯]), meaning "king", or "the king", with the definite article le (royne for "queen").[4][5] It arose as a Norman byname before the Conquest and was passed on as a family name in the Middle Ages.[6]
The Vikings, after having been given their new lands, adopted the Old French language of the northern regions of France and created the Duchy of Normandy. Their descendants, the Normans, took their language and naming practices with them to England, where a dialect of Old Norman called Anglo-Norman was formed.[7]

Originally, Le Roi or Le Roy was a Norman regal name.[8] A man may have had 'kingly' bearing, held a position of authority, was a tournament victor, or it was given as a byname in direct service to the king.[9] This reflects Norman adaptation of social or martial identifiers – a cultural inheritance from their Viking ancestry, forming a family name that was passed down.[10][11]

Matilda of Flanders was Queen of England and the wife of William I ('the Conqueror'), its first Norman king. Matilda's bloodline enabled William to pursue his claim to the English throne; she could trace her descent from the kings of France, the emperors of Germany and even the Anglo-Saxon dynasty... After remaining in Normandy as regent during the months immediately following the conquest, in 1068 Matilda set sail for her new kingdom. Her coronation – described as a 'very rich festival' – took place at Westminster Abbey on 11 May 1068. This was Whit Sunday, one of the most important dates in the Christian calendar... This was a pivotal moment both for the Norman dynasty and the English monarchy. Matilda was spoken of as 'la Royne' by the Normans, which implied that she was a female sovereign in her own right. Her decisive first move as a crowned queen would set the tone for the rest of her reign.

During the later part of the Old English period, two different groups of non-English speakers invaded the country. Both groups were Scandinavian in origin, but whereas the first had retained its Scandinavian speech, the second had settled in northern France and become French-speaking. Both of their languages, Old Norse (ON) and Old French (OF), had a considerable influence on English.

In medieval naming systems, bynames are secondary formations derived from existing words (nouns/adjectives) and serve to distinguish individuals by characteristics such as home district, birthplace, family function, physical traits, habits, or ways of expressing oneself. These formations are part of the anthroponomastic system and provide insight into social identification practices ... Eva Brylla was Docent (Senior Lecturer) in Scandinavian Languages at Uppsala University, specializing in name research. Her doctoral thesis was on the inflection of place‑names in Old Swedish, and she published extensively on both place‑names and personal names. She was formerly the Head of the Department of Names at the Institute of Language and Folklore Research in Uppsala.
