Family Photo

1) Usually these photographs would name the studio on the front or rear of the photo with the location. Knowing the name and location of the studio will narrow the potential ancestors.
2) The youngest child could be a boy even though in a dress. This was common at the time for children to wear such things. I have a family photo of the same period of time (circa 1890-1900) showing a boy in such an outfit, and with his soft features, made to look like a girl.
