Still looking for my great grandfather, NELSON BIRD MCCORMICK, Born between 1840 and 1850 in unknown location. He married Josephine Westbrook, born 1846 in Tennessee. They were the parents of MARY MCCORMICK, born 1870 in Tennessee. On my Grandmother Mary's Death Certificate it lists her father as NELSON BIRD MCCORMICK. Any help will be appreciated.........Bill LaRue
