How to DNA Testing for Ancestry for Beginner Genealogy - Step by Step
Step-by-step guide to DNA Testing for Ancestry for Beginner Genealogy. Includes time estimates, tips, and common mistakes to avoid.
DNA testing can be a powerful starting point for beginner genealogy, especially when you want clues about your ethnic origins and possible relatives. This step-by-step guide shows you how to choose the right test, understand your results, and turn DNA matches into useful family history discoveries without feeling overwhelmed.
Prerequisites
- -A valid email address to create a DNA testing account
- -A mailing address where a DNA kit can be shipped and returned
- -A debit or credit card to purchase a test kit
- -Basic information about your parents, grandparents, and known family surnames
- -A notebook, spreadsheet, or genealogy app to track matches and discoveries
- -Willingness to review privacy settings before submitting your DNA sample
Start with an autosomal DNA test, which is usually the best option for beginner genealogy because it can connect you with relatives from both sides of your family within about 5 to 7 generations. If you have a specific paternal line or maternal line question later, you can consider Y-DNA or mitochondrial DNA testing, but most beginners should not start there. Compare major testing companies based on database size, ethnicity reports, match tools, and transfer options.
Tips
- +Pick autosomal DNA first unless you already have a very specific father-line or mother-line research goal.
- +Check whether the company allows raw DNA uploads from other services for future comparison.
Common Mistakes
- -Buying a specialized Y-DNA or mtDNA test before understanding what question you are trying to answer.
- -Choosing a test based only on sale price and ignoring database size or match features.
Pro Tips
- *Test the oldest living relatives in your family first, because they usually share more DNA with earlier generations and can unlock harder research questions.
- *Label each match by side of family as soon as you can, such as maternal, paternal, or unknown, to avoid confusion later.
- *Use the shared centimorgan total to estimate relationship range, but always compare it with age, family location, and known relatives.
- *Download your raw DNA data if the testing company allows it, then consider uploading it to compatible genealogy platforms to find additional matches.
- *Revisit your match list every few months, because new relatives test all the time and a future match may solve a question that seems impossible today.
