Two thoughts after I closed down the computer last night.

There are some poetical spellings in those songs/poems, especially the 1839 one, so I'll double check this against the printout later, to be sure I got it all (I had to type these in, no cut and paste available for either).

Second, the book I referenced did say that there were at least three poems with this maritime burial theme, and the one I shared here was the only one extant at the time the book I referenced was published (1981). Considering how Chapin's poem was used so thoroughly for "Lone Prairie," the chances might be very good that it was one of those others that got the same treatment for the "Dying Ranger/Soldier" variations. A look through Google Books and JSTOR and other sites with old books and periodicals could take a while, but you might find one or two of those others. I would suggest using keywords from the song variants to see if you can track down the poems.
