We believe this little girl is Joanne (Zirkle) Perkins because she appears in another photograph where her older brother, Lew Arden Zirkle, was identified.
Joanne was born to Owen Nathaniel and Audrey Adeline (Miller) Zirkle.
Two children posed together. The boy in this photograph was identified as Lew Arden Zirkle in another photograph. From this, we have determined that he had a younger sister, Joanne, who we believe is the younger child in this image.
