Good morning:
I am curious as to whom you identify as your oldest known and proven Calvert ancestor is? I see Thomas 1789. Do you have the ancestry further back with projection or a "suspect"?
Further, do you know any male Calverts who would be willing to participate in the Calvert surname project at familytreedna.com?
We are continuing to research using both documentation and DNA for all Calvert family lines. For the Calverts who are Quaker we can document and primary and secondary lines to John c 1580. However there is no proof of genetic link to the Calverts who claim descent from Lord Baltimore. We also have 2 other succinct lines of Ireland.
Let me know and thanks,
David Bell - Coordinator, Calvert surname project,
