Wow!  What a spread of material. And a good way for you to panel the picnic photo!  I will add some thoughts about it.

 

Panel 1  Standing lady at end is Aunt Betty.  Uncle Day behind her, surely.

 

Sitting boy is Telford on the left. Who is boy?  I doubt if Bradley, Rayford, and that bunch were born yet.

 

 Panel 2 

 

Panel 3 Evelyn Metzger beside Mary.

 

Tall couple still look like Koons

 

May to right of boy with bat Uncle Albert?

 

Lady beside Kenny Aunt Zella?

 

Panel 4 (lost track)  Phyllis is sure.  Melvin was two years younger, so not the baby in Margaret's arms.

 

Man behind Aunt Ivy looks like a  Strayer.  Oh, that says Strayers are around.  Of course, Grandma's family.

 

Panel 5  Lady beyond Aunt Ivy looks like Uncle Lester's wife.  Was she living at this time?

 

Note: Man behind Kenny Link is Milt Lohr.

 

That's how I am seeing it now.  Barbara
