John-

I think you're making headway with Stormalong as a pumping shanty for the 1850.

"Fire Maringo" also was mentioned by Nordhoff as a stevedore shanty for screwing cotton, which was may have been used later as a halyard shanty; we have no idea what the original tune was, only the way it was reset to a tune "channeled" by Royston Woods of the Young Tradition in 1967.

Cheerily,
Charley Noble
