I actually wrote an API for handling personal names, because software mangling people's names irked my pedanticism. The fundamental takeaway is that names are ridiculously complex, equivalent to any other part of natural language. For every rule you could contrive there are exceptions, and many more legitimately ambiguous cases.

You shouldn't ever use first/last name fields, because they force users to adapt around your system (many names don't follow this structure). A long unstructured text fields is best, because it can accommodate nearly anyone who's name can be spelled with unicode. Finally always check your interpretation of a name with the person in question, seeing as they're the end authority.
