I scanned this one at fairly high resolution mainly so I could see all my haul of toys (I remember the horse and the jack-in-the-box). Then I sent it to my Aunt with a couple of other photos not knowing it would solve a frustrating family history problem for her.
I had thrown this picture in just for fun with another picture of my Great-Grandparents and a couple of people I couldn't identify for sure. My Aunt named them as well as the location of the photo (in close-by Bountiful!).
The moral of this story is simply that Family History is best when it is not a solo project. Which is sort of the whole point of family anyway.
