My Earliest Photo of my Mother

I thought I had no photos of my mother prior to her high school years. She graduated from high school in 1943. My dad has had her photo album from the 1940s in his house all my life! A few years ago I brought it home and scanned all the photos. I particularly liked the photos because she wrote captions on every one with a white pen, as you can see in the photo above.

For some reason, I've scanned the photo above but had NEVER taken time to study it. This afternoon it caught my attention and I gave it a good look. I'm sure my mother is the second girl from the right. I've added her name to help with the identification.  I'm thinking she might be about 10 years old. What do you think?
