A Bevy of Young Dinas Girls

In this 1930s photograph nearly all of these young girls are named except for one in the back row  LHS! Does anyone have any information about those in the group or where they were at the time?

Back Row. L-R  U/k; Lily Williams; Margaret George (Davies); Sybil George.

Front Row. L-R Orissa Watts; Joyce Richards (Bolland); Hettie Williams (Edwards); Beryl Davies (Lewis).

It seems as though someone was lucky enough to have a tent to play in as a tent peg and guy rope can be seen in the top LHS of the picture!
