sentences:  A great variety of names are attested from the medieval period, falling into the rough categories of Scandinavian (Old Norse), Anglo-Saxon (Old English), continental (Frankish, Old High German and Low German), and East Germanic (see Gothic names) forms.By the High Middle Ages, many of these names had undergone numerous sound changes and/or were abbreviated, so that their etymology is not always clear.Of the large number of medieval Germanic names, a comparatively small set remains in common use today.
