An obscure or archaic term, possibly a variant of 'butler' or an occupational title of uncertain meaning.
Possibly related to 'butler' (from Old French butelerie, wine service) or a completely separate term. Documentation is extremely limited.
This might be a regional pronunciation of 'butler' from a specific English dialect, or it could be from a specialized craft—the frustration is that without written sources, we can't know for sure!
