A growing method to help in genealogical research is DNA. For the past decade DNA genealogy is been gaining ground in the community. DNA testing can determine whether two individuals are related. Descendants believed to have a common ancestor can be tested. The test can help to prove, or disprove genealogical theories. It can also point to genealogical research that has been completed and indicated a family connection. Even where no other family member has participated in a DNA study, the DNA results can point to likely places in the world from which ancestors originated.
