Petty family again

Petty clan, many years ago, Left to right, first row: Leonard (b1924), Opal (b1913), Sarah (b1927),. Second row: Janie (b1918), Viola (b1885), Osmo (b1915), Roy (b1921), MaryJo Johns (bb1913)(wife of Tom), Tom (b1908), and Wallace (b1910). Notes: Their "Red Hills" house is behind them which means the house was taken near Cohutta, in Murray County, Georgia.. The oldest sibling, Georgianne is missing. Maybe she took the picture. Their father William Elijah Joseph Petty died in November, 1935, the picture was probably taken shortly after his death. Why is Osmo is wearing a hat?
