Hello Jack, I read your posting of Neffs, Ohio and saw you are just beginning your research.I grew up in Neffs and left there 30 yrs ago at the age of 19.My whole family is from Belmont & Monroe Counties and so I have a couple of reference books to use from there.I have looked up the Sells surname for you and this is what I found:
From the book Tombstone Inscriptions & Family Records of Belmont Co., Oh by Esther Weygandt Powell:
Hendrysburg CemeteryKirkwood Twp Sells, Frank 1857-1931 wife Alena? 1856-1895
