Carico, Mary Ann, d/o Abel and Elisabeth, b. 4 Nov 1748
The article says "births," but I wonder if this isn't a baptism.

2.  1790 Census.  VA Census destroyed; KY Census not taken (not yet a state).

3.  Census Index:  U.S. Selected Counties, 1800 (Broderbund CD-312):
1800 Tax List Evan, William KY Henry Co.
There was no William O'Nan anywhere on this CD, but "Evan" could be a "mishearing" or a misreading of "Onan."  I checked every William in Henry Co. and this is the only one that comes close.

4.  Census Index:  U.S. Selected Counties, 1810 (Broderbund CD-313).  William O'Nan not found, but he is now in his 50s and Mary Ann is in her 60s.   Perhaps they're living with one of their children, but I have checked the households of what children I could find and none had a senior couple living with them.  I really wonder if they're still alive.  I've seen no source for their death dates.

5.  Census Index:  U.S. Selected Counties, 1820 (Broderbund CD-314).  William O'Nan not found as head-of-household.

6.  Census Index:  U.S. Selected Counties, 1830 (Broderbund CD-315).  Neither William O'Nan nor Mary O'Nan found as head-of-household.
