Looking for information and descendants of William KNOTT and Elizabeth HEMLINGER(1847-1916) who married in ca 1864 and were in Maineville, Warren County in the 1870, 1880, 1900 and 1910 census. Children included Joseph A. and Lillie (Whalen). Lillie had a son named Roy and I believe Joseph had a son named George and daughters, Nellie and Minnie. Thanks.
