Thanks for your replies. I have since found it the orphanage was in Radway (I got the towns mixed up in my mind). We drove past the building a few weeks ago when we were up in the area visiting gravesites.
I will try the provincial archives for sure. Do you know if Radway has a museum?
I also found it was a Catholic orphanage so I will see what I can do about contacting the catholic church as well.
Thank you
Sandra
