Fred Buckley I think was a member of 'Buckley's (New orleans) Serenaders' a minstrel troupe. According to Kilgarriff they were formerley called The Congo Melodists est 1843 by James Buckley (1803-72)and his sons, Frederick (1833-64),R Bishop (1826-67), and George Swain Buckley (1829-79). Disbanded during the Civil War.

I have a later English song book of 'Buckley's Serenaders' so the troupe must have continued using that name in England after the Civil War, obviously without Fred, but presumably still singing some of his songs.
