Individual Details

There is a Belmont Co marriage for Sarah McKim to Lewis C. Shanon, 14 Nov 1855.
But this may not be her.

Knowing that some of the family had moved into West Virginia - I believe the following could be Thomas with his sister Sarah living with his family:
1870 Census: Cross Creek, Brooke Co, WV, Hh 265
Thomas McKim, 37, b. Ohio
Susan, 35, b. Ohio
Leannie, 6, b. WV
Clara, 3, b. WV
Sarah J. 35, b. Ohio (dittoed with the McKim surname)
