The rulers of Babylon, mentioned in the Old Testament book of Daniel, have independent, local, primary sources that confirm they were actual historical figures. Unfortunately, the book of Exodus does not provide the name of the Pharaoh of Egypt. Nor are there any surviving Egyptian sources that confirms the Exodus story.

In the deuterocanonical books of Maccabees (they're in Catholic and Orthodox Bibles), Alexander the Great sets the story in motion.

He's about as historically confirmed as you can get from that period, I think.

1 Maccabees was probably written a little more than a century BCE.

Also: there are war elephants in these books. War elephants. I don't think you'll find them elsewhere in the Hebrew Bible or the New Testament.

Lawrence Mykytiuk recently published a list of 50 people, a popular extension of his earlier thesis.

Part of the problem of historical identification with anyone in the bible is the lack of documentation which is a problem across the ANE in general. About half the names in the bible are unknown outside the bible, although every now and then a new confirmation pops up (in this case of the name, not the person). This is probably due to the poor levels of documentation.
