DNA testing has become a powerful tool for mapping out family trees and uncovering our heritage. I encourage everyone to explore their ancestry—and consider taking a DNA test as a meaningful part of that journey. Each of the companies listed have strength and weaknesses. The general consensus is to test with Ancestry first.
AncestryDNA
The largest database for matches and strong integration with historical records/family trees. Widely considered the top choice for most genealogists.
MyHeritage DNA
Excellent for international matches (especially European, Jewish, and Middle Eastern ancestry), affordable pricing, and powerful family tree tools.
23andMe
Provides ancestry + health insights, with a large user base for relative matching (though less genealogy-focused than Ancestry or MyHeritage).
FamilyTreeDNA
Offers the broadest range of tests, including advanced Y-DNA and mtDNA for deep lineage tracing, plus autosomal (Family Finder). Great for serious or specialized genealogy.
Living DNA
Strong for detailed British Isles and sub-regional ancestry breakdowns, with some wellness insights. Smaller database but unique for certain geographic focuses.
Gedmatch
An online platform for genetic genealogy research, allowing users to upload DNA data files. It provides free comparison tools, to help people explore ancestry across a global database of millions of profiles.
