John O. Marcy was my Great Grandfather. He and his wife, Isabella, and family are listed on the 1860 Census in Lauderdale County, Mississippi. His daughter, Laura Green Marcy, born 1862 in Meridian, MS, was my Great Grandmother. Laura Marcy married James Ruben Bull. Zadoc Marcy and John O. Marcy may have been brothers. They both migrated to West Texas where my Grandmother, Ruth Salome Bull was born.
