Most DNA testing services provide reports that include basic options for determining DNA matches. However, these are not the key focus of the testing service, and they are not designed to offer deep dives into DNA databases to find possible family members or to complete comprehensive genealogy research.
There is a specialized family finder tool available to complete these types of in-depth searches and research. GEDmatch offers a free service that allows users to upload their raw DNA data for use in the system. It is important to note that GEDmatch is used by law enforcement, but users have the ability to opt out of having their data accessed by law enforcement for specific use in developing genomic tools used to identify criminals.
Getting Started
The process to begin searching or building your family genealogy is simple. You will need your raw DNA data from a compatible source, such as 23andMe or AncestryDNA.
Registering for an account includes some basic information and an upload of the raw DNA data. In a few hours, the user will see a Kit ID assigned to their account. This Kit ID is your unique number, which is used to complete one-to-many, one-to-one, and admixture types of searches.
The one-to-many provides information if the sample is a match to others in the database. The one-to-one autosomal DNA comparison is ideal for finding specific relatives by the amount of DNA data shared, while the admixture helps to identify ethnic roots. Other tests are also available that provide more general or specific search criteria.
There is a learning curve in the use of any family finder tool. With a bit of practice, it is possible to trace multiple generations within a family.
