Born in Louisville, KY, Moore was owner of a large grocery store and several houses in Paducah, KY. He was at one time a clerk in the Mileage Department of C. & O. & S. W. R. R. He was also a letter-carrier in Paducah; he may have been one of the first African American mail carriers in the city (prior to 1900).
