On Footnote.com, I was able to find this Patrick Ryan in the St. Louis City Directories for 15 different years. This allowed me to trace his and the family's movements from 1864 to 1881. The 1882 City Directory also allowed me to confirm the date of Patrick's death. With this additional information, I had enough data to seperate the biographies of Patrick and his wife Louisa. See Patrick_Ryan for this additional information.
