Terry, Adam Patterson is listed with his family on the 1850 Jennings County, Bigger Township, census. His wife, Roxanna, is listed as head of household on the 1860 Johnson County census. It is possible he died in Jennings County. Please check your cemetery info for an Adam Patterson or any other male Patterson that would have been born around 1796 and died between 1850 and 1860. Thanks for your help. Jeanette
