I put a list of links to Suffolk Miracle material in thread  The Weeping Lass. All the tune examples in Bronson are from the USA and Canada, but more recently, versions of the song have been found still current in both England and Ireland.

The Little Penknife discussion is at The footboy (Canadian ballad), but I don't think it really has very much to do with The Suffolk Miracle, though there are certainly similarities in the opening verses, which may perhaps have been borrowed from an example of that song such as the one Child referred to.
