People take a DNA test with FamilyTreeDNA.com because they are wanting to learn what their DNA can give them in terms of their genealogical research.
Each type of DNA test offered will bring the tester something new, as will testing different members of the same family bring something new.
This is because of the way that DNA is handed down through the generations.

The goal of this Surname project is to bring all testers with the same or similarly spelled surname together and to learn as well as extend out genealogical research. 
We are scattered all over the world and to locate a cousin or even a "lost family" living in another country is very special.To this end, both men and women are welcome as are their siblings and their parents.
