Font families

I’m trying to replace the sans-serif in this theme. I replaced everything in the stylesheet to Georgia and serif, except the font-awesome prompt and the selections that are keeping the footer from glitching out…But most of it is still sans-serif. I’m wondering if there’s some of it that’s not specified, so it’s just showing the basic default selection or if there’s another file where I need to change the font settings. I figure there’s probably also a way to set a superseding font with custom css input but I haven’t come across what that code would be at this point. Any help would be appreciated.
