Hi, Dewar is a small, small town east of Henryetta, OK, if my sense of remembered geography serves me well (I drove through it last year). I believe Dewar would have been considered a mining town since my father's adopted family (HOFFMAN, NOBLE) and my husband's mother's family (STANLEY) both lived there about the time your McKee did, the 1910 period. And the men in the family all worked in the mines. Coaltown or Coalton is nearby and was also a small, small mining town (I drove through there, too). And Shulter, which is north of Henryetta and south of Okmulgee, is where my HOFFMAN, NOBLE family moved to sometime before the 1920 census. Good luck, Ginger P.S. If you run across the above or the following names in your research, please let me know: MOREY, RICH, PELL.
