Richie - re the Fanning version. I can't see any previews of the Compleat... but if Fanning was the source (as stated), then I'd assume the lyrics are from that time. I can't find out anything about the notebook, so it's not possible to tell what period the notebook spanned. There is a version of Lowlands of Holland on site here from his notebook and the tune is taken from elsewhere, so I presume the songs appear without tunes in the notebook.

It really could do with someone getting a look at the Compleat Nutmeg-State Songster! (As far as I can see it's not listed in Roud - not under Georgey from USA or any Georgie-title from Connecticut. So there's no independent corroboration there).
