Rosowhorne History, Family Crest & Coats of Arms
Cornwall, one of the original six "Celtic nations" is the homeland to the surname Rosowhorne. A revival of the Cornish language which began in the 9th century AD has begun. No doubt this was the language spoken by distant forebears of the Rosowhorne family. Though surnames became common during medieval times, English people were formerly known only by a single name. The way in which hereditary surnames were adopted in medieval England is fascinating. Many Cornish surnames appear to be topographic surnames, which were given to people who resided near physical features such as hills, streams, churches, or types of trees, many are actually habitation surnames. The name Rosowhorne is a local type of surname and the Rosowhorne family lived at Rosewarne estate in Camborne in the county of Cornwall which had anciently owners of the same name, who held the estates until the reign of James I., when De Rosewarne sold it to Ezekiel Grosse, gentleman and attorney at law. According to legend, a ghost pointed out to him a great treasure in the mansion (hidden there doubtless by one of the Rosewarnes) which he appropriated; but the "phantom" so haunted him, that he sold it to his clerk, John Call. 
Early Origins of the Rosowhorne family
The surname Rosowhorne was first found in Cornwall at Rosewarne, now a hamlet north of Camborne. The family resided at Rosowhorne Kaye or Key from ancient times.
"On the bartons of Lower Rosewarne and Crane, where nothing but farm houses now appear, were formerly the seats of two families of these names. But these in the reign of James were sold to Ezekiel Grosse, Esq. after passing through some intermediate hands."

Rosowhorne 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 Rosewaren, Rosewarren, Rosewarn, Rosewarne, Rosewarran, Rossewarn, Rosowhorne, Rosewhorne and many more.
