narrative inquiry or grounded theory

A children's song, Ring around the Rosie, is traceable back to at least 1790 in the United States and 1796 in Germany. It was widely held that it was a reference to one of the last outbreaks of the bubonic plague (The Black Death that struck England in the 1660s). Some folklorists disputed the connection, though this belief in the song and dance's origin was widespread. Assume you were alive in 1790 in England and attempted to find the origins of that song. Would you have chosen narrative inquiry or grounded theory as your methodology? Why?
