According to E. Rossoni, Alberghini belongs to a surname group that may derive from the Lombard personal name Aliberg or Alibergo, documented in Italy as early as the 7th and 8th centuries. In this interpretation, the surname has Germanic roots and originated from the descendants of an ancestor bearing that medieval name. Rossoni also notes a possible connection with place names such as Malalbergo in the Bologna area, suggesting a geographical origin in some cases.

F. De Laurentiis proposes an alternative explanation, linking the surname to the Italian word albergo, originally meaning “shelter,” “lodging,” or assistance offered to travelers and strangers. Under this interpretation, the surname may have originated as a nickname or occupational name associated with hospitality, lodging, or the management of an inn.

Overall, Alberghini may derive either from a medieval Germanic personal name or from the term albergo, preserving a connection with hospitality, lodging, or a place associated with such activities.
