Angela, I have a copy of Daniel's obituary from the Columbus Gazette, Feb. 15, 1905. There is quite a bit of detail in it, including the fact that he lived in Muscatine Co, Orono Twp., at the time of his death. Since Mary survived him, maybe she died in Muscatine County??? Do you have this obituary, or would you like to have me send it to you E-mail? My feeling when I saw the ages on the 1850 census, of Robison family, was that Mary was an older daughter taking care of her father and younger siblings.? Janice
