This photo is from my Great Grandmother, Ruby Waters Huyler's photo album. The only person who's identity is known is my grandmother, Betty Huyler Albea. She's the girl on the right.
The man is in a few other photos, but I don't know who he is. My guess is that he is one of Ruby's Smith cousins. Ruby's mother, Louise Smith Waters came from a large family and Ruby and Betty stayed with them in Greenville, SC sometimes.
