Barker family & unknown Barker male

Top Male picture is my grandfather Thomas Martin Barker, the lady next to him is his mother, Julettie McIntyre Barker, she had a twin sister Lucettie. The man in the picture below I do not know, but I am almost certain he is a Barker also. These pictures were taken in Crawford Co Arkansas at Mountainburg/Turner/Mulberry/Shepherd Springs area.
