I am looking for information on Mary Kearney and her guardian, a Mrs. Rahn. Mary was the daughter of Patrick Kearney who was a sailor on the Great Lakes and lived in Chicago in the 1870s. When he died at sea, a female family friend by the last name of Rahn became the exector of his daughter's estate. Mary Kearney was in a Catholic boarding school. If anyone knows who this female Rahn was, I would so appreciate hearing from you.
