Question for Marlborough High School

I an Ms Begum Soodharry, a Mauritian teacher, I taught in Marlborough High School for 3 years. I would like to have a list and if possible the contacts of my students who were in A level chemistry class and one o level science class in the 1986-1989
I would really love to be in contact and see who they have become.
Please if you Know Trevor who was at that time attending the school tell him to contact me.
