Again, this is one of those old tunes that has been passed around and rewritten countless times - The Folk Process At Work. I have heard it as Flora, as well as Molly; and "when first I came to Ireland," as well as "when first I came to Louisville." Apparently the melody goes back farther than 1839. I really love the version with Mark Knopfler & the Chieftains on the Long Black Veil album.
