Unknown member of Williamson family
This picture is of a young farmer with a young woman sitting near him. In the upper righthand corner, you can just make out an older woman standing in the background. I have another "mystery" photo on this site with a better picture of her holding 2 babies. I don't know who she is either.
This picture was in with a bunch of photos of the Williamson family. It might be Laura Smith Williamson's brother or maybe her son. I have no idea when it was taken or where.
