Sabrina, Have you checked the Davidson County, Tn. Metro Archives search?? The online census may be 1860 and a partial 1850???? There are also early marriage records at the site. What is the name and est. birthyear of your Jackson? Do you think may he is the son of John Jackson and Lovis Koen?? Who did he Marry?? Where did they live?? Sarah Jackson B about 1803 is believed to have a brother named William.. While the proofs I have for my Sarah "Sally" Jackson being the daughter of John Jackson and Lovis Koen are valid, with Jackson being such a common name, additional proofs would be very appreciated!!
