Loved that book, and "Trouble With Angels." They were so funny! (There was the homemakers class where the nun lisped and always said, "thewing" instead of "sewing." My older sister desperately wanted to attend an all-girls academy after she read it.)If your book is pre-Vatican 2, anything goes! Find a catalogue of saints and feel free to saddle your nuns with what you like! Remember Sr. Polycarp in "Where Angels Go, Trouble Follows"?
