No problem at all, Brian, and no discourtesy at all. Child 1 is one of the very few Child ballads that does go back beyond the late 16th century when the ballads we're familiar with were (IMO) starting to be made.
In stating an opinion on oral versions deriving from the broadside, I think I used the word 'probably' and I was definitely talking off the top of my head. I'll have a closer look at the versions you mention now and get back to you. Of course the 17th century broadside is only one stage in the development and there could have been plenty of others that didn't survive. I'm fully aware of examples of ballads that have existed in oral tradition for several centuries seemingly without the assistance of print, but these are few and far between.
