"Peggy" is the nickname for Margaret, and BRAZIER is a phonetic spelling variation of BRASHER — this is one woman and one marriage.  The February date is presumably the date of the bond and the March date that of the actual ceremony (please see my explanation of early marriage records for the reasons multiple dates can be associated with one marriage).  The 1813 marriage dates are clearly the correct ones because Sanders first appears on the tax rolls in 1814 and he has a son born by 1815.  This film is not of the original marriage book.  The Christian Co. Court House burned during the Civil War.  Obviously, some records were saved because the LDS has a film of the second county marriage book, dated 1818-1841.  However, it's clear from the film of the second book that it had endured the fire and is in terrible condition.  One presumes the first book, 1797-1817, was in worse shape because it was not filmed.  The LDS film for 1797-1817 consists of a typescript, with all the inherent problems of a transcription — and this one is known to contain errors.  Whether the transcription was made from a partially destroyed book or the rescued boxes of loose permission slips, marriage bonds, and minister's returns (some of which are still extant for Christian County), I do not know.  It was probably a combination of all of these.  In any case, an error as serious as the duplication of Sanders Thompson's marriage record, with an incorrect year and different variant of the name, is not impossible under these chaotic circumstances. 

2.  1820 Census Index/Images (online at Ancestry.com):  not found, and I searched every page of Christian County, but surely Sanders was in Christian Co. in 1820 because he is on the tax rolls (see below).  He is not the only one known to be in the county and on the tax roles, but missing from the census.  Given the condition of the census pages, it's not hard to imagine that some have been lost.

*This entry makes no sense.  If you don't own a stallion, there is no "rate of covering" (the amount of the stud fee was a measure of the value of the horse — obviously, these people took horse-breeding seriously).

There was no other Sanders THOMPSON in Christian Co., so at first glance is seems a mystery why he would be called "Jr."  However, there was an older Sanders THOMPSON in adjacent Hopkins Co., and the Tradewater River crosses the boundary between the two counties, so it seems reasonable that calling the younger one in Christian Co. "Jr." was in referance to the older one in Hopkins Co.

9.  Family Group Sheet No. 54975:  James Mins Thompson.  Everton Publishers, Inc. (Broderbund CD-14).  Shows the Sanders THOMPSON who married Margaret BRASHER as son of James "Mins" THOMPSON, and this appears correct.  See this chart of the persons on the tax rolls of Christian Co., KY, showing Sanders THOMPSON living on the Tradewater River with James Mims THOMPSON and his other sons. 

The LDS Ancestral File shows one Sanders THOMPSON married to five women, but in reality these are three Sanders THOMPSONs. 

There are two Sanders THOMPSONs in the 1830 census of KY:  one is our subject, the Sanders THOMPSON (b. 1790-95) in Christian Co., KY (who married Margaret "Peggy" BRASHER), and the other is the Sanders THOMPSON (b. 1786/7) in Hopkins Co., KY (who married Ms. __?__, Isabella DOSSETT, and Talitha __?__).  That there is a third Sanders THOMPSON is proven by the fact that both of the Sanders THOMPSONs in KY in 1830 were much too young to be the Sanders THOMPSON who married Eleanor CLARK in 1797 in NC.  Isabella Dossett and Talitha __?__ clearly belong to the Sanders THOMPSON from Hopkins County as they both died in the same county he did (viz., Ozark Co., MO).  The Sanders THOMPSON in Christian County married only once, not twice, to Margaret BRASHER, who is the same person as Peggy BRAZIER.
