If you have never had your yDNA Markers tested, the best way to join the Grau DNA Project and order your test kit is to click here. This link will open a new web page in a separate window. Select the type of test and level of markers to be tested. You will then be taken to the next page, where you are informed that you are about to join the "Grau" Group Project. Click on "order the test kit," and you are on your way to discovering more about your ancestry. Follow each page's instructions and fill in your information to order your test kit.

Another consideration
What company do I test with? Many companies offer Y-DNA testing but may not test as many markers as FTDNA. To help you make this an easier question to answer, you must consider what would be best for you. Here is a Comparison Chart of the DNA testing companies and what markers they test. If you are testing for genealogical purposes, you should always consider the "more markers, the better" phrase. When looking at the Comparison Chart, it is easy to see that FTDNA offers the most comprehensive tests with the most markers. Even if you decide against FTDNA, please use the contact page on this website to request that you be included in the "Genetic Census" of Grau Y-DNA. You might belong to a Family Group or may match a single Grau. If the latter is the case, you will form a new Family Group while at the same time gain a genetic cousin.
