I went to the library today with little luck. Didn't have much time. I looked at Claude M. Simpson's The British Broadside Ballad and Its Music to find early British Broadsides but found nothing there.I agree with Malcolm that, "Go From My Window" is not part of this branch. I found 4 English versions by Sharp (all in 3/2) but they are around the turn of the century like the one posted by Malcolm.
According to several sources "The Drowsy Sleeper originated as a British broadside ballad."
Sharp says "The Silver Dagger" is generally assumed to be American but "it takes its title and some of its details from a British Ballad (Sharp II, p.229)."
Does anyone know of a British "Silver Dagger"? The library didn't have much info that was readily accessible.
What is the British broadside source of "Drowsey Sleeper"? Was that the Bodelian Ballad (1817) posted by Toadfrog?
I've got several different American versions I will try and post at a later date.
