Names on picture are Dorthea, Allie Rayfield, and Elizabeth Lowry.

I believe Dorthea is Dorathy Irine Rayfield, b. abt 1918, and Allie is Allie Mason Rayfield, b. abt 1915. These girls are sisters, the daughters of Thomas Lindon Rayfield and Hattie Curlee.

I'm not sure exactly where Elizabeth Lowry fits in, but there are several connections between the Rayfield and Lowry/Lowery families. Thomas Lindon Rayfield's mother was a Lowery -- Zilphia "Duck" Lowery, married to Peter Rayfield.
