The older couple seated in the front are (1) Great-Grandpa Edward Lafayette Spry and (2) Great-Grandma Sarah Frances Clark Spry (parents of Minnie Belle Spry Trump, grandparents of Emery Andrew Trump, and great-grandparents to Audrey Arlene Trump Kennedy). The young woman holding the little girl on the far right is (3) Gladys Spry (Mrs. Bill Spry), and the child she is holding is likely their daughter (4) Margaret, who died very young. Bill Spry (6) is the young man in the cap who is between the woman in the white blouse and behind a boy in a cap. That boy is (5) Emery Andrew Trump (1905-1962), who was Audrey Trump's father.
