A DNA test can do two valuable things for a Swedish family history: connect you with living relatives—sometimes cousins still in Sweden—and confirm the lines you have traced on paper. What it cannot do is name your parish or build your tree; for that you still need the records. This hub explains which test to choose and why.
Which test, in one line
For most people with Swedish ancestry, AncestryDNA and MyHeritage are the two to consider first. AncestryDNA has the largest database overall—best for finding cousins, especially on the Swedish-American side. MyHeritage is strong across Europe, including the Nordic countries, which helps for finding relatives still in Sweden. Because MyHeritage accepts free uploads of AncestryDNA data, testing at Ancestry and uploading to MyHeritage gives you both pools. Sweden also has a high rate of DNA testing, so Swedish matches are plentiful.
The main options
- AncestryDNA — biggest match database, best for diaspora cousins, integrated with trees and hints.
- MyHeritage — strong European and Nordic reach, a chromosome browser, and free uploads from other tests.
- 23andMe — health-and-traits focus; weaker for tree-building genealogy, and carrying real privacy considerations (see below).
- FamilyTreeDNA — the specialist for Y-DNA and mtDNA, useful for focused surname or lineage work.
On 23andMe: the company filed for Chapter 11 bankruptcy in 2025; a nonprofit founded by its former CEO (the TTAM Research Institute) acquired its assets and it now operates as a nonprofit, but the episode drew lawsuits over genetic-data privacy and legal scrutiny has continued. Your results would not be wrong, but if long-term custody of your genetic data matters to you, read the current privacy terms and know you can request deletion.

A note on Swedish DNA
Swedish results have their own character. Ethnicity estimates typically show broad Scandinavian ancestry, often difficult to distinguish cleanly from Norwegian or Danish, since the populations are closely related. Sweden is not strongly endogamous, so matches behave fairly predictably, though certain regions and the historically isolated north have their own patterns. As always, read the ethnicity estimate as interesting rather than precise, lead with the records, and use DNA to confirm lines and find cousins.
