Item #1: Yair Davidy's account of the migrations of Dan and Naphtali (remember, Davidy is a Jew, who is always trying to equate the tribe of Judah with the Jews. Otherwise, his work is excellent. - Eli James).
Item #2: Linguistic Division of Tribes Into Clans
Item #3: The Tribe of Asher Migrates Into Europe
Item #4: The Euro-Saxons, good encyclopedia article
Item #5: "Israel's Grave Was the Saxon's Birthplace," WH Bennet
It is also worth noting and sharing with your 'jewdeo-christian' friends that there is no attempt at disputing the fact that the Anglo-Saxon, Celtic, Lombardic and Germanic etc, peoples are true Israel even by the likes of Davidy et al.
