I'm trying to discover leads to who people are in some old photos. I notice one person will have a hand on anothers shoulder or be standing to the right or left in a photo. The photo I have attached is of my great Grandfather and Grandmother. I am wondering who the man on the far left and the woman on the far right are. There is some disagreement in my family regarding this matter. Some say the man is the son of my great grandparents and the woman his wife - but some say he is actually my grand mothers brother. Any ideas?
