Thank you for that reference. I will follow up on it. I don't know if Catherine Ryan was married, single, or widowed. I am assuming that she was alive in 1891 at her sister's funeral, as the newspaper did not say she was the "late" sister.
(I have a Joseph Ryan (godfather) at a baptism in 1880 at St. Mary's Catholic Church in Bismarck,D.T., so maybe she is part of that family. I appreciate your help!
