These two charmers are in my collection of unidentified pictures. The picture was found among my dad's items. Based on what I think is the date (1883-1893) I suspect that one of these two girls is my dad's mother (Bess Coulter) and the other is one of her sisters Harriet or Haysel Coulter. Bess was the older of the 3 girls thus she would be the one on the left. Bess was born in 1883, Harriet in 1891, Haysel (no birth date). Unlikely the 2nd girl is Harriet because of the difference in ages. There was also a brother, Camillius (no birth date).
No markings on the photo but on the back are five number 4 written in pencil
