Albert E. Brumley, the evangelist, took copyright on a large number of arrangements, including some of those also "arranged" and copyrighted by the Carters.
One of these is "The Picture on the Wall;" Brumley's copyright of 1938 is handled Stamps-Baxter (or whomever controls that company now).
"Two Little Orphans," and several descendants, subject of a Mudcat thread, was copyright by him and M. Lynwood Smith in 1966.
Arrangements of "Home on the Range," "Listen to the Mocking Bird" and "Grandfather's Clock" were copyright in 1966 by Smith for arrangements in "Lamplightin' Songs," published by a Brumley company.
"Cowboy's Dream" (Last night as I lay on the prairie) is another with a Brumley arrangement copyright.

Not posted yet, but "When the roses bloom in Dixieland" resembles "When it's springtime in the Rockies."
