Show ContentsIago History, Family Crest & Coats of Arms

The notable Iago family arose among the Cornish People, a race with a rich Celtic heritage and an indomitable fighting spirit who inhabited the southwest of England. While surnames were well-known during the English medieval period, Cornish People originally used only a single name. The way in which hereditary surnames came into common use is interesting. As the population of medieval Europe multiplied, people began to assume an extra name to avoid confusion and to further identify themselves. Under the Feudal System of government, surnames evolved and they often reflected life on the manor and in the field. Patronymic surnames were derived from given names and were the predominant type of surname among the Celtic peoples of Britain. However, the people of Cornwall provide a surprising exception to this rule, and patronymic surnames are less common among them than other people of Celtic stock, such as their Welsh neighbors. This is due to the greater influence of English bureaucracy and naming practices in Cornwall at the time that surnames first arose. This type of surname blended perfectly with the prevailing Feudal System. One feature that is occasionally found in Cornish surnames of this type is the suffix -oe or -ow; this is derived from the Cornish plural suffix -ow. is a patronymic surname that came from the personal name James, which itself is a version of the ancient name Jacob, which means supplanter.

Early Origins of the Iago family

The surname Iago was first found in Cornwall, where there is some debate of the name's origins. One reference lists that the name was "from the Spanish Iago, which must have crossed over into Cornwall at some early period." 1 While another states "whether it derives from the Celtic-British Iago, and signifies James or from gago or jago, a spear and pledges for battle; however, the name was of ancient use in Britain; for Galfridus Monmuthensis tells us of a king named Jago, before Julius Caesar landed in Britain, that reigned twenty-five years, and is buried at York." 2

The parish of St. Erme in Cornwall was an early home for the family. "The barton of Innis or Ennis, was at an early period possessed by the Opies, who held it so late as the days of James I. during which period it was sold by them to an ancestor of Samuel Jago, Esq." 3 It is generally thought that the name Jago is Cornish for the name James and in Welsh records as Iago. 4

Early rolls point to a variety of spellings and entries of both as a forename and surname: Jago filius Ytel listed in the Pipe Rolls of Hertfordshire in 1185; and William Jeago in the Assize Rolls for Shropshire in 1221. 4

Iago 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 Jago, Jagoe, Jagow, Jeago, Jego, Mac Ego and many more.
