Which Reminds Me

Yes, I vaguely remember that during eighth grade one of the novels that Mrs. Richardson read aloud to us, during the half-hour time allotted after lunch, was about some Jewish people from Eastern Europe. The heroine was the maid whose job was to meticulously polish the marble stairs every day. Later she escapes to the United States where she meets some other people who convert to Christianity and they all live happily ever after in Canada. I forget what the book title was, I noticed it somewhere years ago but forgot again, do not remember who they were.
