Mystery Grandmother

This picture is of Lula Francis Autry, sister Anne and the unknown grandmother who raised them. Trying to identify the grandmother and any information on Anne. On the back of the photo it says "Anne Autry (Self). Not sure if that meant she married a Self or that was to indicate that she was her self. Any help might break the Brick Wall on who the parents of Lula Francis Autry were. Lula married Charles Franklin Browning in 1898 in Greene Co., Arkansas. Lula was born Aug 1883 in AR according to 1900 census. No further information on Anne. Thanks for the help.
