But who is in the middle? A neighbor, relative? Their grandmother? Not their mother.
I wish I knew. Maybe my cousins will be able to identify.

On the left my Aunt Edna and on the right her sister Charlotte, my maternal grandmother. The woman between is unidentified.

Instantly obvious on first sight, you have a strong resemblance to Charlotte Ruth. Genetics on parade.
Beautiful picture, hope someone can identify her.
I think you resemble your Aunt Edna. It is frustrating when we can’t figure out who everyone is in a picture. Hope your cousins can help.
I’m curious about the big barrel on the right. Clothes washing?
The unidentified woman looks fierce, eh? No nonsense. Lol.
