I'm not happy with the ages of the children; they don't mesh well enough with the censuses.

1a.  Anon.  1966.  Marriage Index:  Ohio, 1789-1850.  Liahona Research, Orem, UT (Broderbund CD-400):

Culp, Jacob	Lamb, Mary	7 Sep 1807	Fairfield Co.
Culp, Jacob	Rudebaugh, Mary	9 Aug 1810	Fairfield Co.

Could these two be the same Jacob?  I think it likely, which means Mary RADABAUGH, not Mary LAMB, is the mother of most of the children and that Mary RADABAUGH is the Mary in the censuses, and that Mary RADABAUGH is the Mrs. Mary CULP who died in 1856 and is buried in New Salem Cemetery.
