William Sharp McKechnie, Magna Carta: A Commentary on the Great Charter of King John
“ A “barony” at the Norman Conquest differed in almost every respect from a “barony” at the present day. The word baro was originally synonymous with homo, meaning, in feudal usage, a vassal of any lord. It soon became usual, however, to confine the word to king’s men; “barones” were thus identical with "crown tenants"—a considerable body at first; but a new distinction soon arose between the great men and the smaller men among their number (between barones majores and barones minores) . The latter were usually called knights (milites) , while “baron” was reserved for the holder of an “honour.” ”
