Have I found Uncle Killough?

Remember this photo? And the copy I had was labeled "George" (3rd from left), but it doesn't look the least bit like all the other pictures I have of George. But a granddaughter of Bernice's assured me today that it is definitely NOT Bernice. I'm sure she is right -- she knew him well. So...

Oh, wait... There's another brother -- Killough. The only picture I have of Killough was taken when he was 3 years old. He died a young man in 1943. The photo above was very likely taken before then. So... could this actually be Killough? 

I hope so. I'd love to know that I have a picture of him as an adult. I only have one picture of his wife, and not a very good one. And the only pictures I have of their son is when he was a little boy (he died a young man, too). 

Did any of you know Killough well enough to confirm that it's him in this photo?

Here's his 3 year old photo:

Looks like the same face to me. (Or am I just wishful thinking?)
