Looking for members of the Stelliou family of Potamos

I am trying to locate members of the Stelliou Family from Potamos, in order to exchange information about the history of our ancestors.
My great grandfather Panagiotis Stelliou left Potamos in the 19th century and established a commercial business in Varna, now in Bulgaria, Black See. His son, (my grand father) Nikolaos Stelliou-Tsirigotis married a Bulgarian woman (Anna Petkova) in Varna, and came as refugee in Greece from Bulgaria in 1911 to Almiros, Thessalia, where he died soon after. His wife Anna and four children (Marika, Evanthia, Sultana and Panagiotis) moved to Thessaloniki in the 20s and settled in the suburb of Nea Varna. My faher Panagiotis (1913-1982) graduated there from Law school in the 30s, was employed in the Ministry of Public Welfare and was transferred to Athens in 1959.

I would appreciate if I hear from people that share the same family name - rather rare in Greece- and would like to exchange information about possible common ancestors.
