I'm a bit concerned about suggesting this, Jim, but could they be fake-type photo.
I had a photo sent to me, supposedly my 3x great. I was suspicious as her granddaughter had exactly the same hands. I then discovered that the granddaughter was used to dressing up for a niece who was a photographer. More oddities were discovered. It was definitely not 3x granny. It even fooled Prue for a while.
