S. IL Davenport children?

My Aunt said that these two could be Davenport children. They were from Southern Illinois, and she believes they live in Anna, Saline County, IL. But...she is not sure. If anyone could help me out I sure would appreciate it. Thank you!
P.S. I have found a postcard to my G-Grandma Josephine (Travelstead) Norman, and the picture is of two small girls, it is signed: "Your neice, Annie Davenport. I also have that picture posted on this site.
