Bjo Trimble's birth name is Trimble, Betty Jo.
If you mean when was Black Betty written, no one can say for certain. It was a British pub song in the early 1700's, then a patriot march song during the Revolutionary War. Later it was sung by slaves and/or prisoners on chain gangs. If you mean when was it first recorded, that would be in 1933, by a prisoner known as "Ironhead" Baker, but it didn't really make it. The first really popular recording was by another prisoner, "Lead Belly" Ledbetter, in 1939. The most famous version (imo) is the one by Ram Jam, recorded in 1977.
