I emailed the School Sisters of Notre Dame and they checked the registry for me and they found my grandfather and siblings on the registry. They gave me the dates they were admitted and released, as well as the Nuns that were there and what their jobs were.He was there in 1936 to 1939 Thats all they gave me but my grandfather was pleased with the dates. Here is the email I contacted. Hope this firstname.lastname@example.org
Sister Joan Helm is the Sister that emailed me the info. Good Luck!
