Is it coincidence or something impish in the air that gives us four threads about songs with 'Nancy' in them at the same time?

The songs are:

And canst thou leave thy Nancy?
Lovely Nancy
The Wreck of the Nancy Lee
Queen of the Heather.

I said long ago, in a thread about 'Pleasant and Delightful' that it is an affectation of the upper class that country girls, especially saucy ones, are named Nancy. I still hold that opinion.

In 'The Queen of the Heather,' we find versions in old Scots dialect, then Joe Offer submits a version in standard English where the shepherdess has been converted to a Nancy. I feel that once the heroine has been converted to a Nancy, that song is over as a folk song.

Any further views?
