Thanks, Bryan. This helps confirm what I have about O.L. Mahoney. You are correct that he eventually moved to Arizona. Oscar moved first to Murphysboro, Jackson County, Illinois, married Virginia Rosson in 1870, and they both became physicians. They appear in the 1910 Census for Phoenix, Ward 2, Maricopa County, Arizona. Oscar died 12 Jun 1915, burial in Greenwood Memory Lawn Cemetery, and Virginia died 04 Apr 1924, burial also in Greenwood Memory Lawn Cemetery.

This is a great board.
