If you're still looking for information, your Alton, b. 9 May 1884, is my 2nd great grand uncle (according to Ancestry). Alton was listed in the obituary as surviving brother of Coma Lee Pribble, b. 1886. (I have a copy of this obituary, but I have no information on which newspaper it was in.) As you may have seen, several siblings' death certificates list the parents as George Pribble and Mary Ella McDaniel. Note that some records spell Coma as "Comer," but that is incorrect.
