David N. Brown is on the 1870 census for Williamson Co. IL.
Looking for information on this family. David N. Brown b. 1829 TN., Louisa J. Grant Brown (wife) b. 1836 TN., children: Martha C. Brown b. 1859 TN., David N. Brown b. 9/18/1862 Williamson Co., Mary Brown b. 9/18/1862 Williamson Co., Henry S. Brown b. 3/30/1870 Willismson Co. IL. David Sr. was in the civil war, the family was living around Fredonia
Twp. when he went into the civil war. I think the family was in Williamson Co. early 1860 but havn't found any records on them in the 1860 census.
