"Maryland, My Maryland" appears in Allan's Lone Star Ballads, A Collection of Southern Patriotic Songs Made During Confederate Times, Burt Franklin, New York, 1874 (reprint 1970).
This collection, made just after the War, is an excellent survey of the Confederate songs. It covers the western contingents, e. g. Hood's Texas Brigade, Song of the Texas Rangers, The Santa Fe Volunteer, and others.
