The Maritime Folk Songs piece at p63 you quote is not a version of Child 248. It's a version of Roud 22568 Night Visiting Song (My Master Title). I have studied all versions of all 3 ballads, Grey Cock, Willy-O, and Night Visiting Song and apart from a few Irish hybrids they are easily separated. I might add (IMHO) the Irish hybrids are vastly superior to any of the individual ballads.

I can easily scan you a version of MSF if you want to see it for yourself.
