Do you happen to have the name of the nun, who answered your request? I presume she's in Montréal. I could always get in touch with her since I live on the south shore of the city. I've checked the Banque Nationale du Québec & haven't been able to find any pics of Cathedral St nor of the Hospice or School. That area is downtown Montréal & most of the bldgs must no longer exist. It's best to try to get as much info as you can from the Gray Nuns since they've sold part of their Mother House to Concordia University so they're slowly (over 10 years) moving out. Most are aged & sick, averaging 72 years of age, I believe. Maybe we could find a nun, who taught at the École Ménagère or who remembers the Hospice St-Joseph provided it still existed after 1924. I'll keep looking around the Net to see if I can find anything, but it was mostly the Sisters of Providence, who had Hospices. The gray Nuns were into founding hospitals & orphanages in Montréal. As far as I know, they've all been sold. Like all other religious communities, their membership is diminishing quickly so if you want info, it's best to get in touch with them pronto. Good luck!
