Is this a photo of five McCauley siblings?

One person in this photo is my Aunt Gladys. She is on the far right facing the little boy, and she’s the only one in the picture I can identify without a doubt.

I’m 90% sure the young woman standing is Aunt Vernon. Gladys and Vernon were my dad’s sisters and the two oldest of Will and Verda McCauley’s 11 children. This photo is from an album that belonged to Verda’s brother, Jimmy Hankins. The other three in the picture are probably also Will and Verda’s children, but I can’t say for sure which ones—at least, not by looks alone.

Identifying the boy seems like the best place to start since his age is easier to estimate than the others. Will and Verda had four sons—Joe, John, David (my dad), and Ralph. Let’s say the child in the photo is two or three years old. Joe and Ralph can be ruled out right off the bat. Joe was too close in age to Gladys and Vernon. Ralph died when he was 10 months old.

The boy in the picture looks more like John than David, and John’s age works out the best. John was born in 1921. When he was two or three years old, Gladys was 18/19 and Vernon 17/18. By the time David was two, Gladys and Vernon were 23 and 22 and had five children between them. Best guess is the toddler is John.

Now for the other two girls. Will and Verda had three daughters between Vernon and John — Vashti, Liz, and Lois. Lois was only three years older than John and the youngest girl appears older than five or six. Liz was seven/eight and Vashti 14/15 when John was this age. They are the only possibilities for the other two girls (if these are indeed McCauley siblings).

I’m reasonably satisfied this is a photo of Liz, John, Vashti, Vernon, and Gladys.

The photos below, taken within a few years of the photo in question, are all I have for comparison. What do you think?
