Have started a project, one of which has as a goal to determine whether VanVliet and Flatt are actually of the same origin. If you are a male and your last name is VanVliet, seeing how you stack up against others of your same surname may be the jumpstart you need to sort out your heritage. I intend with this project to solicit Flatt, Van Vliet, Van Fleet, etc. We have 2 results back so far with 2 more pending at http://www.halcyondays.com/Flatt/FlattDNAProject.htmhttp://www.halcyondays.com/Flatt/FlattDNAProject.htm (click on See Test Results). The DNA test is a saliva kit test that, after being taken and returned, takes about 6 weeks to get results back from. Take a look and please email me about participating. If you are not a male Van Vliet, but know of a relative that might take the test as your representative, that is another option.
