changing site title font in Pilcrow?

Can anyone help with changing the font of my site title? It’s currently on the default font, which as far as I can tell is Georgia. I want to change it to either Baskerville Old Face or Copperplate Gothic (or anything similar – just needs to look like them).

I’ve searched the CSS, but can’t find anything that either specifies the font, or looks a likely place to insert override html.

Would be most grateful for any help. My site – The Skull Illusion
