You probably already know this but Wikipedia has a disambiguation page for Camerton (I'm sure it didn't refer to the Mongolian pop band):
* Camerton, Cumbria, a village in England
* Camerton, East Riding of Yorkshire, a village in England--this one is mentioned in the Doomesday Book, but no mention of Boteliers. The head of the manor is Burstwick.
* Camerton, Somerset, a village in England
Nothing at all about Ireland.
