Sanderson/? Young Girls

Sanderson/?Young Girls
Contibuted by: Dana Holden January 2006

On the front row are Lura Sanderson with two Young girls on either side. 
The back row is Flossie Sanderson (taller) and Johnnie Kelly. 
The Sandersons' brother married Dessie Young
but I would like to know who these two Young girls are. 
This photo was made before Lura's death at age 16 in 1904.
