Just looking through American versions, as you say many of them are just fragments, but there are some interesting versions. Regarding the hybrids with 'Gypsy laddie, looking at the NC versions it's pretty obvious Gypsy Laddie is the host ballad with a couple of verses from SCS grafted on.

Here are the longer ones I have seen so far.

Sharp's Franklin Va version 7v, standard SCS apart from the last verse which seems to be unique in N America, and occurs in the Crawfurd version.

Catskills p479 from the Edwards brothers 7v again appears to have a unique last 3 stanzas in N. America although they are found in most British printed versions.

Hubbard's Utah version 6v has nothing special

Eddy's A version 7v has the 'where do you live' verse but this is found in a couple of other shorter US versions.

Her B version is quite unusual 8v in that it has the Scottish 'What is your name' verse, again unique in N America, and it also has some pretty extensive incremental repetition that Peter Buchan would have been proud of.

Creighton's Nova Scotia version, 6v, contains a verse from Trooper and Maid.

Peacock's 5v version is pretty standard English.

I use the word unique only with the reserve that there will be other versions I don't have access to currently.
