Here's the lastest list from 1950 by Coffin: http://bluegrassmessengers.com/a-critical-biographical-study.aspx

I haven't finished proofing this page yet. There are a couple missing, for example 52. King's Dochter Lady Jean

The only known traditional US version of this ballad titled "Queen Jane" was sung by Sara Cleveland. It was recorded by Sandy Patton in the early 1960s.

I think published an updated edition later. Reed Smith did some early lists.

I've only made it to No. 63. It seems that most of the ballads so far date back to the 1700's in Scotland/England.

The most likely sources of 1700s Child ballads in the US would seem to be old periodicals, newspapers, diaries, and family histories. New bits of information will pop up from time to time- you have to realize that ballad scholars and those interested in ballads have been looking for this information already- and it seems to be lacking.
