This project accumulates Y-DNA (male only) results data for selected families with ancestors who were documented residents of Sumner County, Tennessee before the Civil War. This allows for analytical comparisons and genealogical connections, in some instances. You MUST have a 37, 67 or 111 marker YDNA test prior to requesting to join this project. Your YDNA test must represent the direct male ancestor that resided in Sumner Co. TN prior to the Civil War. You MUST provide the basic documentation showing that your direct male ancestor resided in Sumner County Tennessee, prior to the Civil War, when you request to join this project. This is NOT an autosomal DNA or mitochondrial DNA project. Please do not ask to join if the only test you have is autosomal or mtDNA.
