You only need to contact the author(s) if you want to relicense the code.
You don't need to relicense anything to include it in your work, that's
the beauty of the BSD license. You just need to retain the original
copyright and license notice. Especially since our version of the BSD
license doesn't have the advertising clause.
If you just keep these files (and any of your contributions) licensed as
BSD there won't be any confusion and you can include it in your project.
