Are you looking for a free to use option?

There's a bunch of unique serifs here on dafont: http://www.dafont.com/theme.php?cat=502

And there's always google fonts: https://fonts.google.com/?category=Serif

Try DS Type Maga (not free)

Some Free options: Serif Beta
(This one's a great font)

or Permian

Or.... like GSM suggests, just browse dafont and google fonts using his links and see if there's something there you can use.
