Way Back When-sday

This is one of the few old photos in the ones I have with me now that doesn't have any information written on it or that I don't know much about. I know it's a picture of Mama holding Stephen and I'm standing at her side. The dark blue Ford Galaxie 500 in the background is our car. We appear to be dressed for something like church or some other dressy gathering. I would guess the photo is from around 1968 or 1969.
So we have the start to a great story.... anyone want to fill in the details?
