How to Choose an Ancestry DNA Test
What to Look For
- 1. Database size is the single most important factor for finding DNA matches. AncestryDNA's 25M+ users dwarfs all competitors.
- 2. Ethnicity regions vary by company. 23andMe leads with 2,000+ regions. If you have specific heritage interests, check which company covers them best.
- 3. Genealogy integration matters if you are building a family tree. AncestryDNA and MyHeritage offer the best tree-building tools.
- 4. Raw data access lets you upload to third-party tools like GEDmatch for expanded analysis. Check if the company allows downloads.
- 5. Privacy controls vary widely. Check if you can opt out of DNA matching, law enforcement matching, and research programs.
Testing Strategies
- 1. Start with AncestryDNA for the largest match pool, then upload raw data to MyHeritage, FamilyTreeDNA, and GEDmatch for broader coverage.
- 2. Test both parents if possible. Each parent contributes half your DNA, and testing them helps phase your matches into maternal and paternal sides.
- 3. Test oldest living relatives first. They carry DNA from ancestors you may not have inherited. Grandparents are gold mines for genealogical research.
- 4. Combine DNA with records. DNA testing finds relatives; census records, birth certificates, and immigration documents tell their stories.
- 5. Consider Y-DNA or mtDNA for deep ancestral questions. These tests trace direct paternal or maternal lines back hundreds or thousands of years.
Common Questions About Ancestry DNA Testing
Why do my ancestry results differ between companies?
Each company uses different reference populations (groups of people with known ancestry from specific regions) and different algorithms to estimate your heritage. Results are most reliable at the continental level. For sub-regional estimates, consider testing with multiple companies and looking for consistent patterns.
Can I find unknown relatives through DNA testing?
Yes. DNA matching compares your autosomal DNA against other users in the company's database. Close matches like first cousins are highly reliable. Distant matches (4th cousins and beyond) become less certain. Many adoptees and people with unknown parentage have successfully identified biological relatives through DNA testing.
What is a centimorgan (cM) and why does it matter?
A centimorgan (cM) measures the total amount of DNA shared between two people. Higher shared cM means a closer relationship. For example, parent-child pairs share approximately 3,400 cM, while first cousins share about 850 cM. Most ancestry sites display shared cM on match pages to help you estimate relationships.
Are DNA ancestry tests worth the money?
For genealogy enthusiasts, yes. A $99 AncestryDNA test can break through brick walls that years of traditional research could not. The ethnicity estimates are fun but should be taken as approximations. The real value is in DNA matching, which can connect you with relatives you did not know existed and confirm documentary research.
