This piqued my curiousity, so I went to look into the origins of the place name. It's somewhat obscure, but seem to come from an Anglo-Saxon word meaning roughly rocks/heights/nooks so is probably linked to a geographical feature somewhere in Hallamshire.
It's also a pre-Norman surname (there are pages of genealogical stuff about this) based on the place name. And presumably, like any surname, it has been used more recently as a first name on the normal pattern of transference.
