The Emergence of the Sympathetic Witch in Twentieth-Century Culture

I’ve been wondering lately how neatly the sympathetic witch corresponds to the rise of the sympathetic vampire in twentieth-century culture?  I was named after one very memorable good witch, Samantha Stephens below, played by Elizabeth Montgomery (my parents were huge fans). I think her dates are 1964-72. The show was written by Claudio Carvalho, Rio de Janeiro, Brazil.  This is of course the same era that gave us I Dream of Jeanie (1965-70) A show in which an American astronaut finds his life vastly complicated when he stumbles on a bottle containing a female genie!! I’d love to know your thoughts on when the figure of the sympathetic witch first emerged in the twentieth century and why?
