Sorry, none of those names rings a bell. There was a nun that visited my grandmother many times, but I don't know her name or if she was related or not. I have a box of gift cards my mother kept from her wedding shower. With it is a wedding congrats card signed "Mr & Mrs Joseph Dubiel". When I asked my mother who that was (a few years before her death) she couldn't recall. It's signed in standard North American school script not in Polish script, so it was probably signed by someone else.
