Okay, then Davin's Official Native American Name shall now be: "Jordi Sven Pale Hawk". :)
As for further insight on the significance of "Davin"... If you've already been to that website that PriaposLovs gave you, then you've done a pretty thorough job already on your own. I have just two reference books that mention the name "Davin":
From *The New Age Baby Name Book*, by Sue Browder: "Old Scandinavian: 'brightness of the Finns,' who were once thought to be the most intelligent people of the North. Popular in Scandinavia."
From *Baby Names: A New Generation*, by Barbara Kay Turner: "Davin is a French form of Davyn (DAY-ven, DAV-en), which is a Welsh variant form of David."
Okay, now give me *your* full name so I can give you a Native American Indian anagrammed name of your own. :)
