I did not think there could be more than one set of Blevins in a small place like Oneida with a name like Armp...Was I surprised! I looked in the census for you today but nothing makes sense (including ages, spelling and fathers), but I will list for you in the hopes it might help you or "another Blevins" looking for someone.
1900 Census-Scott Co., TN: Millard Blevins, Head of Household, b1842; Melvina, wife, b1853; John C. b1874; Marion 1879, Darby 1880, Liza 1881, Mary 1885; Armp 1886; Sarah D. 1887, Burdell, 1890.
1910 census ("trying" to pick up same family and sibling names you mentioned) Isacc, HOH, b1867; wife Adlade, 48; John, Armpstard, age 22; Burdell, Cooper, Epram, Hattie.
I also found in 1900 census:
Abe Blevins, 1870; Poly, 1870; Thomas, '84, Mary, '87; Martha, '89; Armp, 91; Henry (?) '94; Charly, '95; Daniel, '97; John M., 1900. Excuse spelling, dates-I copied and typed what I saw! Please let me know (firstname.lastname@example.org
) if you ever determine we're in the same line.
