It's my understanding the city of Paris was named after the Celtic
Parisi tribe, if not directly then indirectly. That's a pretty strong link, and suggests that most of todays Americans, having common Celtic roots, are related to the French. {Sigh}. So are most of the "new Americans" coming over the southern border, via their Spanish Celtic links.
This site has more information: Parisi details.
Most Western Europeans are quite interrelated with Romance and Germanic blood -- Romance being French/Italian/Spanish and Germanic being Dutch/English/German/Celtic (I'm beginning to regard Celts and Germans as being more interrelated than not)
