The Gentile Surname Project invites researchers to find their common heritage through sharing information and DNA testing. All Gentile, Gentil, Gentileschi, Gentili, Gentilini, Gentilucci, Jentile, or any variation thereof, men who have fathers, grandfathers, great grandfathers back to your oldest known great grandfather with the same last name Gentile (or any variation thereof) are eligible to join the Gentile Surname project. Men from anywhere in the world may join our project.

All DNA marker values may be added to YSEARCH.ORG to facilitate finding related Gentile cousins.
