Gateside Secondary School - 1965

The only picture I have of my secondary school, is of the musical we put on at the end of every year.  This on is of the Sound of Music taken in 1965? When we immigrated to Australia we lost the trunk with all the school things. ~ Marion Beaman (Nee Mackenzie)
Unfortunately I have a very bad memory with names but I will give it a go.

Sitting - (1) Steven ?, (2) Marion McEwan, (3) ? (4) ? (5) Marion MacKenzie (Me), (6) ? and (7) Wilma McMillan? And Maria was Helen Gardner.  It would be great if other people could recognise any of the others.
