Kytrad- It's seems likely that the lyrics you shared are related.
Here are some notes from the Henry Reed Collection on the Hog-eye man:

For comparison, see Bayard, Hill Country Tunes, #75 "Hog Eye an' a 'Tater"; Sharp, English Folk Songs from the Southern Appalachians, vol. 2, 360 (#250) "The Hog-eyed Man" (Clay County, Kentucky), 361 (#251) "The Jackfish" (Callaway, Virginia)

Although a "hogfish" is a salt water fish it could be related to "hogeye" somehow. Note that "The Jackfish" was included in the tunes compared.

Pinetop- Without "Drifting to Far From Shore" my grandfather, Maurice Matteson, played the lap dulcimer and Appalchian folk zither. He did "ballad bagging" programs from the folk songs he collected mainly from Nathan Hicks, Beech Mountain, NC. He was a contemporary of Niles, Mellinger Henry, etc.
