Aldigerus colonus, homo sancti Germani; Johannes colonus et uxor ejus colona, nominations Sarra, homines sancti Germani, habent secum infantem i; Erlebaldus colonus et uxor ejus colona, appointments Dodilberga, homines sancti Germani Isti très tenent mansum ingenuilem i, habentem de terra arable bunuaria xv, de vinea aripennum De avena modios ii; ova xlv. Cetera similiter. .. ". (see also ALDEGHERI). additions provided by Stefano Ferrazzi The origin of this surname is to be found in the medieval name Aldigero, the Italianization of the Germanic personal Aldiger, which, composed of the terms alt (old, wise) and ger (spear), can be translated as old spear , an expert lancer (see Lanzavecchia); other sources, on the other hand, maintain that the root Alder derives from the ancient high German adal (noble) and, consequently, the name Aldiger should be translated as noble spear, noble lancer. In conclusion, therefore, it is a question of the surname of the personal name of the progenitor.
