Do we have the same concept about family as ancient civilizations did?

I think that the concept of family we have nowadays is quiet similar to the one ancient greek civilization had because their believes and conception are the begginings of the western modern civilization culture, so in other words like I said both cultures the anciet greek one and the modern western society are very similar and they concepts in this case about family are the same basically, without saying that some concepts have change and will continue changing while time goes on.
