There's a good article on the BBC news site today outlining how adoptees are using commercial DNA testing companies to try to work out their biological surname. It can be found at http://news.bbc.co.uk/1/hi/sci/tech/7459578.stm
For more information on how DNA can be used in genealogy, I've written a couple of articles on the subject in the past for Your Family Tree magazine, which I have subsequently adapted after publication and placed online for free access. The first is a beginners guide to DNA, which can be found at the Talking Scot forum entitled A Beginners Guide to Genetic Genealogy ; the second is a users guide for the groundbreaking DNA Ancestry service which is on the Scotland's Greatest Story website, entitled DNA and Genealogy.
It is important to remember that DNA use in genealogy is not going to provide a magic solution to a brick wall you might have on its own. Despite a lot of the hype, it is simply a tool that can help to smash a brick wall - you will still need good old fashioned research to help the process!
