This is an English medieval locational name. It originates from either the village of Wearne in the county of Somerset, or from the village of Warne in Devonshire. It is also possible that the name could be residential, from residence at a warren, since this is the meaning of the name. "Factory farming" is not new, the monks of the various abbeys in particular practised intensive farming both of animals and fish many centuries ago, and this surname refers to places where the practise was carried out. The derivation is from the pre 10th century French 'Warenne' meaning strictly 'a game preserve', suggesting that the word was probably introduced by the Norman-French after the 1066 Invasion of England. In the modern idiom the name is spelt as Warne, Warnes, Warn, Wearn and Wearne. The first recorded spelling of the family name is shown to be that of Jervase de Werne, which was dated 1273, in the Hundred Rolls of city of London. This was during the reign of King Edward I of England , known as 'The Hammer of the Scots", 1272 - 1307 Surnames became necessary when governments introduced personal taxation. In England this was known as Poll Tax. Throughout the centuries, surnames in every country have continued to "develop" often leading to astonishing variants of the original spelling.
