I have been researching the Slagles in Wayne Co. for over a year now looking for a clue to my great-grandmother Nancy Slagle Gregory (abt. 1860-1885).
Here is some info that may help you on your Slagle/Martin family.
Etty Slagle 3/23/1885-6/16/1927 d/o Moses Slagle & Elizabeth Slagle. She married Emerson John Martin b. 10/26/1884.
Their children (that I know of):
Leo b. 1909 m. cousin, Flora Slagle
May b. 1910 m. Marsh Abbott
Dovey b. 7/1/1912 m. Jim W. Abbott
Charlie b. 1915? m. Artie Martin
Lizzie b. 1917 m. Clarence Griffin
Edd b. 12/1919 m. Vina ?
Dorothy b. ? m. Mr. Dobbs
Hope this helps. Do you have names of Charlie and Artie Martin's children? Have you ever heard of a Claiborn Gregory or Emberson Gregory connected to the Slagles?
