The Bold Fisherman was collected in 1905 by H.E.D Hammond and published in The Hammond And Gardiner Manuscript which in turn was published by Frank Purslow in his Marrow Bones. The tune and song were taken down in Combe Florey, Somerset and St. Marys' , Dorset, the tune being attributed to Gulliver, Mrs and wthe words to Mr Roper respectively.
As to the song itself, it is not the so unusual story of an aristocrat in workman's clothing chancing on a "pretty maid" and carrying her off to matrimony.
This song may be found in the Tyneside Maritime Chorus songbook
