DNA testing is trendy, but probably here to stay. It can help solve genealogical brickwalls. In genealogy we use it to assist our research with adoption cases (finding relatives), identifying war brides or children of war, defining migratory paths of ancestors (point of origin), surname evolution and changes, and as a tool for medical genealogy with the assistance of a Geneticist.

FamilyTreeDNA and 23andMe hold large databases. FamilyTreeDNA has over 640 thousand participants, and 23and Me has an excess of 500 thousand. Once a person has been tested on a site (FamilyTreeDNA, 23andMe), as the databases grow, additional genetic matches are found. Participants are notified of possible matches (kinships) by email, allowing for an opportunity to meet new cousins, share family histories, etc.
Due to the extensive immigration, of all nationalities, into the USA, DNA testing is often used to determine ethnic origin. Although genealogy research has long been the USA 2nd top hobby (next to golf) thanks to popular TV shows like Who Do You Think You Are? (TLC) and Finding Your Roots (PBS) demonstrating successes of DNA testing as an effective tool for solving family mysteries, the demand for these tests has increased in recent years.
(Bragging rights: Kathleen Brandt of a3Genealogy is a genealogy researcher for both of these TV shows.)

At a3Genealogy we analyze DNA test results as part of our genealogical services. DNA complements, confirms and verifies our genealogy paper-trail. We usually do not perform a DNA tests until after an extensive research project has been completed (except perhaps in the case of adoption or unknown parentage). We often suggest DNA testing to private clients, or for heir-ship cases, where we search for heirs of an estate.
