ROCHELLE RIGDON

Of uncertain origin, probably a feminine diminutive form of the French boy's name Roch (from Germanic hrok ‘rest’), borne by a 14th-century saint, patron of the sick. This girl's name is little used in France, though widely used in the English-speaking world. It may in part represent a respelling of Rachelle.

Apparently an altered spelling of English Rigden, which Reaney believes to be from Ricdun, a reduced form of the personal name Ricardun, a pet form of Richard. There is no evidence for it as a habitational name: in medieval documents it is never found with a preposition and no relevant place name has been identified.
