Who are these two people in the third opening of Attack on Titan?


In the third opening of Attack on Titan we see a man and a baby holding hands.
Does anyone know who these two people are? I can't remember seeing them in the
manga.

Or -if they are not "real" characters- what does this scene want to allude to?
I can't think of any symbolism in this picture... [![two people holding
