I still haven't found my gg-grandfather, James M. Bailey. However, I have found that he died after his brother Taylor Lewis Bailey on 27 November 1930, as Taylor's obituary stated James was living in Colorado. I have had no luck in finding any record of him in Colorado records (several men of the same name turned out not to be him). I also know now that he died before his sister, Mrs. Sarah Jane Bailey Wilson, who died 16 January 1941.
As it turned out, the 1910 census was a distraction; his wife wasn't widowed, but divorced.
