I have started a DNA Project for the Cunard-Conard (and various spellings)lines....especially those from Thones (Tuenes) Kunders of Germantown PA. Descendants on this line started the Cunard Cruise line (Samuel Cunard) and Charles Conrad, the astronaut is also an descendant.
You can view this project's goals at:www.familytreedna.com/public/Cunard-Conrad
This covers any spelling. A few of the variations are on the site.
