Sarah does not appear in the 1850 census with her parents, so either her birthdate is wrong or the census is wrong.

5.  1870 Census Every-Name-Index/Images (online at Ancestry.com, Image #11 of 21 — indexed "Patterson D Wermers"):  Allensville P.O., Allensville Pct., Todd Co., KY, p. 316A, PN 11, 81/81, enumerated 26 Aug 1870, official enumeration date 1 Jun 1870 (extracted by Diana Gale Matthiesen):

Wimms Patterson A	63	M	W	farmer	400	100	Virginia

Haddox Charles W	27	M	W	farmer		2100	do
______ Sallie B	20	F	W				do
______ Mary	3/12	F	W		10,000		do	Feb

I have no explanation for why Mary has 10,000 worth of real estate(!), except to assume it's enumerator error.  I would also assume that the figure belongs on the next column down, for the head-of-household there, except that the next household is that of a black farm laborer.

I am perfectly aware of what the 1850 Census record shows on the page linked below, but I assure you that the child of Patterson & Sally Ann Mimms Wims was NOT "George S Wims, m, age 7"!  http://dgmweb.net/FGS/W/WimsPattersonA-SarahAnnMimms.html I have seen the same record, but know it to be completely false! That child named George was actually a GIRL named "George ANN Wims"  - She was my gg'gm, who m. Joshua Johnson; their daughter Mary Wims Johnson (Called "Madje" as an adult, short for "Mary J") m. Thomas James McReynolds and had four sons.  I thought you would like to know, since there is no way you could possibly check out any corroborating data for every listing in your data base.
