Ella Bell & Percy Merrick collected the version of Lucy Wan in Penguin Bk of English Folk Songs from Mrs Dann of Cottenham, slightly edited and augmented as related in the notes, which claim it as the only version found in oral tradition in England.

Cottenham happens to be just a few miles from where I live, between here & Cambridge. As I pause momentarily from typing this I look out of my study window at literal Cambridgeshire Fenland.
