Amongst the old photos I have inherited is a one that I believe is of my great-grandmother, born in 1857. This is it, showing the front and back of the photo. I have another photo which I think could be of the same person, but taken a number of years later. I'll add that photo separately to this post (as I can't seem to attach more than two images). Both are wearing the same necklace and earrings, and look similar.
I’d be grateful for any help with dating the photos. Do others think they might be the same person? Thanks,
Ian
