The big question at this point would be "where did the Tannahill Weavers get the version of which they recorded an arrangement?"

Did they credit any source on their record? No acknowledgement seems to appear on their website.

Their text appears to be a shortened form of the one that is in the DT as THE GYPSY LADDIE. There it is credited to "Songs and Dances of Scotland, Thomson", but it appears to be the text that Ewan MacColl collated mostly from traditional examples collected by Gavin Greig, and recorded set to a tune he said he got from his father; though I don't think that MacColl used a refrain. It isn't immediately obvious where the tune with the DT file came from; it is similar to MacColl's and to Jeannie Robertson's, but the notation is not the same.

A little looking around suggests that this and a number of other DT files are copied from a book by one Liz Thomson; regrettably, traditional sources are not acknowledged in the DT transcriptions. It appears that Ms Thomson did not bother to credit her sources (though I would be pleased to be reassured on that point) -if that is the case, then nothing she printed can be assumed to be genuine.
