Wigan Album

This photo shows a group of teenagers from Ince/Wigan during a holiday to Blackpool. Hannah (Annie) Matthews (my grandma) is on the back row (far right). Gladys Hilton is on the back row (third from left), and the four girls on the front row (from left to right) are: Emily Rutter, Doris Hilton, Agnes (?) and Irene McCracken. Before she died, my grandma added most of the names to the back. Can anybody put names to the others?
