A chaplain or religious official, though this is an archaic or variant spelling; more commonly a surname.
Variant or derivative of 'chaplain,' from Latin 'cappellanus' (keeper of the cape of Saint Martin). As a surname, it typically derives from this occupational ancestor.
The root 'cappellanus' comes from an actual cape—Saint Martin's cape—which was so venerated that people who guarded it became a distinct religious order, eventually giving us the word for any religious official!
