Hope you find what you need!
The convent was actually next door to Conister Trust I think!
I had a great time there as a wee girl. As you looked at the building from Finch road it was divided into two , the right side was where the nuns lived. the left side was the school with three classrooms. The nuns quarters had the most beautiful stain glass window at the back over looking Douglas Bay.
It is offices now, ?? accountants, pity, it was a great school but all good things usually come to an end!
