Hi,
On your project... When transcribing IGI records..?? make sure your only using records extracted from local records and not submitted by a member or other person. Reason? submitted by person can have errors where as the other is a real record..

Now to add to your one name study??!! I'm from the Lost Colony Genealogy and Research Group. WE are also interested in Bertie: from website
Bertie, Peregrine -- 1585-1586 - Associated with venture, not necessarily passengers
WE have nothing more on this individual and would appricate any leads you might get. WE are also interested in anyone with this surname who will dna test. You can test via the project and get a group discount on tnhe price for testing with a group.

See our website:

Good luck with your project, you might try andd see if there is other DNA surname projects for the surname...
