"When First Unto This Country" was recorded for the Library of Congress 1934 from the Gant Family in Austin Texas by John and Alan Lomax. It was commercially recorded by Ian & Sylvia, Jerry Garcia & David Grisman, Phil Ochs, Peggy Seeger, Mike Seeger and The New Lost City Ramblers. I learned it from The New Lost City Ramblers on their NLCR Volume 2 album.
