It is innaccurate to say as Q does above, that this song and "The Lass of Roch Royal," Child #76 are interrelated.

Newer versions of this song may well contain floating verses from the other, but that happens with many, many songs- and does not mean or imply that the originals are interrelated.

I'm interested to learn more about this song and its many much-altered variants, so thanks for linking the threads, Q.
