The photo is believed to be around 1912-1915. The two girls on either end are believed to be Emma Hedge and Ivis Hedge (it's not certain which girl is on which end). The two girls in the middle are Malta Gill and Vesta Gill (it's not certain in what order). These girls were first cousins to each other. If you can identify the order of the girls, please contact Jamie Neal, firstname.lastname@example.org.
