What's Your Name?

What I know: This is another from cousin Mel Ferrer's collection; some readers may remember it from Facebook.  We know that the gent in the shadows is Olin Ferrer. His son Owie (Robert Olin Ferrer) is in white on the left of the man; son Hame (Powell Raymond Ferrer) is on the far right. I believe the young boy to the man's immediate right is Joseph Grace. Do you know who this is?
