I feel your pain! My grandmother needed help in that regard as well. I have one photo of my grandfather with an unknown older couple which is labeled on the back, in pencil, "RJ and wife". My grandfather wasn't RJ, so that must have been the other man in the picture, and thus presumably the woman was his wife.
That photo's well-labeled by my grandmother's usual standards...
