The fragment of "bark" verse came from Minnesota.
It seems to be from a variant of "Jonny Boker or the Broken Yoke," 1840, and its allies "Goin' Down to (Lynchburg) Town," etc. and interwoven with "Jim Along Josie" and its allies. Variants wherever English is spoken. In collections of Negro songs as well.

Charles Bolles, who robbed Wells Fargo, seems to have taken (or been given) the name Black Bart from Bartholomew Roberts, the pirate.
