Hi, I would recommend to have a look at:

Arjava, Antti. “Paternal Power in Late Antiquity.” Journal of Roman Studies 88 (1998):

147–165.

Thanks.. will do. But still looking for more.. so please others if you know drop me a note.

I think worth consulting might be also: A Companion to Families in the Greek and Roman Worlds, ed. by Beryl Rawson (Wiley 2010), and perhaps also Geoffrey Nathan, The Family in Late Antiquity (Routledge 2012), if this is not a bit beyond the scope.

A modern Greek father will carry some remnant attributes of what his ancient ancestor was like. On that supposition, I would say the ancient Greek father would be much stricter over his children than the Roman father. He would offer more guidance, will make sure children follow a plethora of customs/beliefs to the letter, something that a Roman or any other would not go to that extreme.

Having lived elsewhere besides Greece, there is no other place like it. Very strict with customs, tradition and history.

The problem with deducing ancient Greek practices from modern ones is the long influence of Ottoman control and the influence of Islamic practices that were violently imposed by their Ottoman conquerors. 

I believe that the most striking difference is the Roman father's legal right of "ownership" and power, including the right of "life" and "death", over his children, based on a Roman family law entitled "Patria Protestas"; something that certainly did not happen with a Greek father.

I would also add that "Patria Protestas" was abolished in the Eastern (Greek dominated) Roman Empire, i.e. the Byzantine Empire.

Yes, very much the point I am interested in. Could you point out some secondary literatureon this? Thanks.

In the study of Andrea Lentakis "paterna paternis-Materna maternis in post-Byzantine law" magazine Miliaka vol B' (Athens 1985), pp. 285-486, Greek unfortunately, there are multitude comparative reports and documents
