THE WRAGGLE-TAGGLE GYPSIES is mentioned in A History of Music in England by Ernest Walker (Oxford: Clarendon Press, 1907):

But historical doubts need not hinder us from enjoying the music that, within the last ten years or so, has begun to pour in upon us from all parts of England ... [such as] ... 'The wraggle-taggle gipsies' (Somerset Folk-songs, vol. i) ....

I have been unable to identify any book with the exact title "Somerset Folk-Songs" so I suspect he meant "Folk Songs from Somerset" gathered and edited with pianoforte accompaniment, by Cecil J. Sharp and Charles L. Marson (London: Simpkin, 1905).

The latter book doesn't seem to be viewable online.
