Rance is a diminutive of Randolph, Lawrence. 1) From the Old High German “Randwulf”, composed of two elements “rant” (rim, edge of a shield) plus “*-wulfaz” (wolf). 2) From the Latin “Laurentum” (wreathed / crowned with laurel), which in turn derives from “laurus”, meaning “laurel, from the place of laurel trees, laurel branch, laurel wreath”.
