According to North Carolina fiddler Bruce Greene*, the tune was originally called Boatin' Up Sandy (referring to the Big Sandy River in eastern Kentucky) and was renamed by Civil War Confederate soldiers in Morgan's Raiders while they were camped on the Big Sandy in Pike County, Kentucky.
Sally Goodin ran a boarding house there and allowed the soldiers to camp and play music. To show their appreciation of her kindness, Morgan's men renamed the tune in her honor.
