The test involves rubbing a specially treated cotton swab inside your mouth, and then you send it off in the mail.

In fact, the only painful part of the test is the cost, normally $200, but DNA Ancestry is offering a half-price test through September 30, 2008. With tax, this test comes to about $118. (I paid full price for our test, and I think it was worth every penny. You guys are getting a great deal for half the price!)

We've had three DNA matches so far, all linking to Nicholas Wren and Margaret Bell of Virginia, but really, we've got so many more Renn lines out there, wouldn't it be great to have a DNA sample from every single one?

These DNA tests will only test a tiny part of your DNA: the Y-chromosome, which is passed down from father to son. If you are a female Renn you cannot take the test. However, you can ask your brother, father, uncle, or other male Renn relative to take the test for you.
