Corrected entry: They named the brothers based on alphabetical bible characters, but, not having an "F" name, they improvised with "Frank"incense... But there are enough F names in the bible, Felix, Flint, and even more if you count "Ph" names like Phillip and Philemon.

Correction: First off, they only used names from the Old Testament. Second, they obviously don't count "Ph" names since those start with a "P". "Felix" only appears in the New Testament and "flint" does not appear as a proper name, but just the hard rock. There are in fact, no men in the Old Testament with a proper name starting with "F".
