Passavant

rangavilla, (1266) raingueville, (1287) passavant, see passavant in Old French. In toponymy, the meaning is perhaps "superior, located aboveErnest Nègre, General Toponymy of France" in relation to valleys, laval. For Passavant-la-Rochère and Passavant-en-Argonne, the link is perhaps direct with the war cry of the Counts of Champagne, the Champenois lords of Passavant having inherited their nickname from their military prowess and given their name to their land.
