My dad knows it from my grandfather. I believe it was recorded on an old 78. I can probably get the majority of the words from my dad. The Jealous lover of green valley was sung by Vernon Dalhart: It starts, Way down in Lone Green Valley. There is also a version called Blue-eyed Ellen. I'm 30 years old so this ballad is a little beyond my years. 70 years olds would probably know it, It was popular I believe.
