victor.library.ucsb.edu. However, www.78discography.com does not assign authorship.
According to wikipedia, A P Carter died in 1960, which would put this composition in copyright until 1st January 2031.
According to the Old Weird America blog:
Legend says that when A.P. Carter first met Sara, she was singing with the autoharp “Engine 143″. He was coming around her home selling fruits and she was just 16 years old then. Soon A.P Carter would marry her and make her sing the songs from her family’s tradition and the ones he collected around the hills of Virginia.
Harry Smith's Anthology booklet states that "The ballad was probably composed by a worker in the round house at Hinton, West Virginia".
The above makes the claim to authorship on the record label doubtful.
