I previously reported that there wasn't any "John Hart" listed in the 1810 Census who was living in Henderson Co., Kentucky. I stand corrected.
Apparently, there is a John Hart listed in Henderson Co., Kentucky in the 1810 Census, but his name was indexed as "Hast" over at familysearch.
What is even more interesting is that listed beneath him is "Anna Hart" which under the circumstances can be none other than the person known as Nancy Hart.
There is a problem however. Strangely, only one male person is clearly marked. There may or may not be the remains of a "1" for over 45 in the female column but it is very faint and partially obscured if it even was there at all.
So, if we assume that this is indeed Nancy Hart than she did not pass away until after 1810.
However, in the 1820 Census there is an "Ann Hart" listed as living in Henderson Co., Kentucky and being over 45. Under her listing is a listing for a Thomas Hart.
In John Hart's will filed in Henderson Co., Kentucky, in 1821, John listed a son Thomas. Presumably, the Thomas listed in the 1820 Census is his son.
What we now have is possible evidence for the belief that Nancy Hart under her actually name of Ann/Anna did live in Henderson County until at least 1820.
