The Jagow history begins in Cornwall, a rugged coastal region in southwestern England. Quite distinct from Devon, the adjoining county, Cornwall had its own spoken language until the late 18th century. The Jagow history began here. The manner in which hereditary surnames arose is interesting. Local surnames were derived from where the original bearer lived, was born, or held land. Unlike most Celtic peoples, who favored patronymic names, the Cornish predominantly used local surnames. The Jagow family originally lived the personal name James, which itself is a version of the ancient name Jacob, which means supplanter.

Early Origins of the Jagow family

The surname Jagow 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

Jagow 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.
