Thanks to all who've responded so far. I'm not sure I'd be inclined to use the bulk of the Child Ballads for lullaby source material — Matty Groves? Little Sir Hugh? Tam Lin? —but these people were a rather gruesome lot, weren't they? Actually, part of the difficulty of this is that the Salem of the 1690's was already a very different society from 1620's Plymouth. It's an interesting challenge because the period culture from across the pond is late restoration, a very different kind of sensibility. But again, thanks, and keep those cards and letters coming, folks.
