Kahl is making it more precise and states that Arvanite groups were involved in the local society during the period of outward migration: Die durch die Auswanderungen entstandenen Bevölkerungslücken füllten zugewanderte orthodoxe Albaner (Arvaniten) & Viele�Arvaniten�nahmen�auch�verschiedene Hilfsarbeiten�an,�die�wegen�der�Abwanderung�von�Zagorisiern�sonst�niemand�hätte ausführen� können. Simply stating after 15th is wp:OR Alexikoua (talk)
