From the looks of the weather, this must have been a March 9th anniversary picture. I've tried to figure out who is who, see if I'm correct, and supply the missing names:
Back row, l to r, Ed Johnson, Mother, George, Orville, Dad, Alvin, Oscar
Middle row, l to r, Jerrold Johnson, big space, Delilah, Alva, Grandma, Elna, with Grandpa in front, and Sofe with Alvin, Jr. (Bun).
Front row: Elizabeth, Louise, Annella, Peggy, Dwight, Dean, Stan, Cal
Those of you with sharper eyes and better detective skills will probably figure this out.
