RE: Ohio Boatman –– No lyrics or music and the title keeps changing ever so slightly but it's always the Hutchinsons.

“Perhaps too large a proportion of their programme is devoted to painful subjects to be acceptable in this careworn land of ours; at least one or two catches sung with great neatness and an Ohio boatman's Glee, (a far-off cousin to 'The Canadian Boat Song.') fell upon the ear very cheerily after the graver ditties.”
[The Eclectic Magazine, Vol.7, 1846]
Hutchinson Family Singers

Note: The 1845 tour of great Britain was by the Hutchinson Family quartet. There was a much later political adaptation of Emmett's De Boatmnan's Daunce for Abraham Lincoln's run, but nothing c.1840s as yet.
