HRE Map

I am looking for a map and the names of the 350 counties of Charlemagne's Empire. I'm kicking around an idea where after the HRE is establlished Charlemagne and his three sons are removed leaving the counts to hash out who is next.

Just cause I'm a history major, "The Holy Roman Empire" was founded by Otto, not Charlemagne.

But Carolus Magnus was crowned an Emperor and ruled a vast territory, some of which Otto also ruled.
