The last name "Eirene" likely originated from the Ancient Greek name "Εἰρήνη" (Eirḗnē), which means "peace" or "serenity." The name has been used as a given name for both males and females in ancient Greece. Today, it is still used as a given name in modern Greece and Cyprus. Over time, the name may have been passed down as a surname through generations, possibly due to its positive and peaceful connotations.
