Spooky New Englanders?

I'm trying to think of spooky authors, artists, etc associated with New England to use in PR for Raks Spooki--something along the lines of "a regional showcase of dancers from the land of H.P. Lovecraft, Edward Gorey, ..."  Any suggestions for other personages?  There's also Stephen King, who is a little more commercial than I would really like to reference, but at least he would represent Maine.  I'd also like to stay away from people like Lizzie Borden or events like the Salem witch trials--more of a focus on the creative than the destructive, you know?  Thanks for any suggestions...
