Have you noticed the link:  How the European Map Has Changed Over 2,400 Years found on the SAGA homepage just above the Database updates?   It provides a cleaver overview of how the map of Europe has changed with population/empires.  It is general but puts population movements into a context that is easier to comprehend (in spite of its general macro view).   Hoosierly yours, James G.
