Alfred on the left. Klaus and Walter on either side of Walter, and Benno and Marianne on the right. (see description) The young girl in front of Alfred might be Veronica, Klaus' oldest, but I'm not sure. Michael is standing just to the left of Walter.

Also, I never noticed, until I started working with the picture, that Klaus and Walter B are looking in different directions, can't see each other, but are using the same hand motions to touch their noses. Maybe there is something to that "twin" thing.
