Umm. Joe, looks like you might be a little out of practice on the HTML. Maybe you can get joeclone to fix it?
About the time the new Lutheran Hymnal came out, I was told about the tracing of the author of this work.
I found this as the title page from 1939: Let all things now living : four-part chorus, with descant, for mixed voices : traditional Welsh melody / Harmonization and descant by Katherine K. Davis ; [words by] John Cowley.
The Lutherans were trying to very thorough & checked with Davis to get help in locating the original author. Presumably this was to get copyright permissions. She fessed up.
From records in OCLC that I'm looking at, it looks like she did something similar on the Little Drummer Boy. Carol of the drum / Katherine K. Davis ; Czech carol freely transcribed by C.R.W. Robertson. Notes: Later known as The little drummer boy. C.R.W. Robertson was a Davis pseudonym.
