|Genetic Genealogy (DNA)|
The ability to test DNA easily and inexpensively has revolutionized genealogical research. It is possible to prove relationships that otherwise would have remained impossible to solve. Many researchers are finding lost cousins; some are getting results tackling illegitimacy questions. It pays to test several relatives, and compare their results with others.
Companies offering DNA tests|
AncestryDNA has a massive database, which makes it possible to find other people who have matched your results in some way. That means they are related. Ancestry's results are limited to autosomal tests, but that is likely to be enough for many researchers. The results allow you to determine the strength of the relationship.
FamilyTreeDNA offers several types of tests, including ones designed to help a person trace the male-male-male line (YDNA) and the female-female-female line (mtDNA). FTDNA has comprehensive tools to allow for the comparison of your matches with other people who have tested.
