However, according to the Where Dead Voices Gather blog, "'Ommie Wise' marks the first song on the Anthology based on a verifiable historical event. In 1807, Naomi Wise was drowned by her lover Jonathan Lewis […] 'Ommie Wise' is a slightly fictionalized account of the murder, reportedly written shortly after the event itself. An early 19th century version of the text has been discovered."
The Roud Folksong Index classifies this song as a version of Roud 447, and a Roud number search obtains a number of versions collected prior to the recording of Grayson's version, dating as far back as 1874, and across a wide geographical area (N Carolina, Kansas, Missouri, Kentucky).
In any case, according to wikipedia, Grayson died in 1930, meaning that this composition is public domain either as a traditional folk song or since 1st January 2001.
