I have a hard time telling the Jones sisters apart. I think that's Louise (Jones) Maxwell in the front, sitting down. Standing behind her is Julia Jones and Mary (Jones) Spann.
I'm not sure who the younger woman is, with her arm around Lou. Perhaps it's a daughter of the man on the right, who I'm now suspecting is Newton Franklin "N.F." Jones (the brother of the three sisters). But because there's no identification on the reverse, it's hard to say for certain. If the younger woman is a daughter of N.F., she would be either Edna Jones Hillman, Bema Jones (later Bema Jones Pickens) or Ethel Jones (later Ethel Jones Anderson, I think).
Kids, do your future descendants a favor, and annotate your family photos thoroughly.
