Looking for relatives of Nikolaos and Maria Bilikopoulos from Maramara

Hello,
I decided to google our last name and came up with your site. My grandparents names were Nikolaos and Maria Bilikopoulos and they emmigrated to Nea Palatia, Attikis, Greece from Maramara, in I believe around 1915.
Apparently, some of their relatives moved to Australia. My father Dimitrios would be very interested in finding these people.

Please respond if you know of them or how the name Bilikopoulos ended up in your site. There are not too many of us, therefore my curiousity is peaked.

Thank You very much
Maria
