Many names emerged before the development of writing, or evolved from oral traditions, so when we investigate the origins of names, written records are of limited use.
Modern scholars rely on a host of techniques to overcome these difficulties, but researching names of truly obscure origin involves a blend of scholarship and educated guesswork. Though it is common to encounter two or more competing theories on the heritage of some names, in this case our research has yet to uncover any explanation of the name's original meaning.
