I thought #3 looked like Hunter. After my grandparents sold the farm they moved to Hunter, and Grandma worked in the school cafeteria. My Mom's youngest sister graduated from Sylvan Grove after Hunter HS closed.
My Mom graduated from Codell HS in 1950, she had also attended Bunker Hill HS. I was at a family reunion in Codell (maybe 1988) and someone asked where I was from and I said Indiana, she said "You must be one of Patty's boys". And she was right.
