Bluy History, Family Crest & Coats of Arms
The birthplace of the surname Bluy is Cornwall, a rugged peninsula in southwestern England that is noted for its strong Gaelic traditions. Even though the usage of surnames was common during the Middle Ages, all English people were known only by a single name in early times. The process by which hereditary surnames came to be used is intriguing. As the number of inhabitants of Europe swelled, people began to assume an extra name to avoid confusion and to further identify them. Under the Feudal System of government, surnames evolved and they often reflected life on the manor and in the field. Although nickname surnames were rare among the Cornish, they did occasionally adopt names that reflected the physical characteristics or other attributes of the original bearer of the name. The name Bluy is a nickname type of surname for a gentle or merry person. Further research revealed that the name is derived from the Old English word blide, of the same meaning.
Early Origins of the Bluy family
The surname Bluy was first found in Cornwall and Devon, where the name could also have been derived from the Cornish "blyth" as in blyth wolf. 
The "Blighs have been settled in Cornwall from the Norman Conquest to the present time. Norden mentions a branch of this family as residing in his time at Botaden in South Petherwin, in which house their arms still remain. When the Duke of Norfolk held a session of heraldry in this county, the Blighs resided at Bodmin. The Earl of Darnley is a branch of this family. The late John Bligh, Esq. and Admiral Bligh, are descended from the same common stock."

Bluy Spelling Variations
Cornish surnames are characterized by a multitude of spelling variations. The frequent changes in surnames are due to the fact that the Old and Middle English languages lacked definite spelling rules. The official court languages, which were Latin and French, were also influential on the spelling of a surname. Since the spelling of surnames was rarely consistent in medieval times, and scribes and church officials recorded names as they sounded rather than adhering to any specific spelling rules, it was common to find the same individual referred to with different spellings of their surname in the ancient chronicles. Moreover, a large number of foreign names were brought into England, which accelerated and accentuated the alterations to the spelling of various surnames. Lastly, spelling variations often resulted from the linguistic differences between the people of Cornwall and the rest of England. The Cornish spoke a unique Brythonic Celtic language which was first recorded in written documents during the 10th century. However, they became increasingly Anglicized, and Cornish became extinct as a spoken language in 1777, although it has been revived by Cornish patriots in the modern era. The name has been spelled Bligh, Blighe, Bly, Blye and others.
