You might be better off enumerating "goodness"...
/^
([A-Z][a-z]+)+ # first name, consisting of any
number of AbAbc, handles "LaDawn"
\s+
( # middle name (optional)
[A-Z] # at the very least, has a capital letter
(
\. # ends with either a dot
| # ... or ...
[a-z]+([A-Z][a-z]+)? # the rest of a name
)? # but again, that's totally optional
\s+
)?
([A-Z][a-z]+)+ # and a last name, following the
same convention as the first (McGraw)
$/x
