Rippon, Galle Teachers trip (around 1948)

This was a Rippon College, Galle, Teachers trip to Yala during the late 40's.
Unhappily I dont know most of the names.
My mother is Peace BeeBee (she was a student at Sacred Heart Convent, Galle (facebook), around 1932-1942). Photos while at Sacred heart convent here, and here.
Please do let me know if you recognize anyone.
