This is a photo of Sallie (Dickson) Ward, my grandmother's grandmother. My grandmother was raised by Sallie since her own mother, Nora (Ward) Dickson, died when she was only 8 months old. Sallie lived to be 99 years old and lived her entire life in Perry County,Tennessee.
My grandmother told me this was a photo of "Mary Ary, Tom Ward's daughter." Tom Ward is one of Sallie's sons. He did have a daughter named Mary, who would've been about a year older than my grandmother. So, it is likely these first cousins grew up as close friends in Perry County. However, I don't have any information on Mary Ward after the 1930 census when she was 15 years old.
The only Mary Ary in Perry County has been attributed to other parents by researchers. There is also a Mary Erie in the 1940 census in Wayne County, Tennessee who might be Tom's daughter. Either way, more research is needed!
