As a pure spiritual, "I Ain't Gonna Grieve" was found in St, Helena Island and in South Carolina. I don't have copies. Also reported from Georgia (White).

"I Ain't Gwine Grief Muh Lawd No Mo'" - Ballanta-Taylor, St. Helena Island Spirituals, p. 64
"Ain't Gwine Grieve My Lord No More" - Diton. Thirty-six South Carolina Spirituals.

It seems to have been taken over, changed and largely spread by white gospelers; then many secular derivatives developed.
