It’s a two-step process: Take as many DNA tests as you can. Your results will be matched to others in company databases who share common DNA with you.
How can I trace my father’s DNA?

A commons question I’m asked is, how many generations does DNA go back. If you’re using an autosomal test such as AncestryDNA, 23andMe, or MyHeritage, you’ll generally go back 6 to 8 generations. Assuming 25 years per generation, you can expect 150-200 years of DNA information by taking an autosomal DNA test.

The 99.9% Accuracy Statistic on Ancestral DNA Tests According to Dr. Brandon Colby MD, Medical Geneticist & Preventive Medicine Expert, “Test takers should be aware that the accuracy of the ancestry tests depends on reference populations, and not all tests will accurately represent your family history.”
