A DNA test can be a wonderful complement to Norwegian family history—connecting you with living cousins across the vast Norwegian-American diaspora and in Norway itself, and helping confirm the lines you have traced on paper. But the tests differ, and Norwegian ancestry has its own quirks: ethnicity estimates that blur across Scandinavia, and a diaspora concentrated in particular databases. This guide explains which test suits Norwegian ancestry, and—just as important—what DNA can and cannot do for your research.
What DNA can and can’t do
Set expectations first, because this shapes everything. A DNA test can connect you with genetic relatives who share your ancestors, offer an ethnicity estimate, and confirm or challenge the paper trail. It cannot, on its own, build your family tree, name your ancestral farm, or tell you precisely which part of Norway your family came from. The real power comes from combining DNA with Norway’s superb records: the test finds the cousins and the evidence, and the records turn them into a documented family history. Treat DNA as a powerful supplement to records-based research, not a replacement for it.
AncestryDNA: the biggest database
For most people with Norwegian ancestry, AncestryDNA is the first test to consider, for one overriding reason: it has by far the largest DNA database, which makes it the best tool for finding relatives. This matters especially for Norwegian-American research, because the large Norwegian diaspora in the American Midwest has tested in great numbers, so your cousins—the ones descended from the same emigrant family—are more likely to be found here than anywhere else. AncestryDNA also integrates with the largest collection of user family trees, which helps identify how a match connects to you. It is the natural starting point for diaspora cousin-hunting.
MyHeritage: strong in Europe
MyHeritage is the strong second choice, and for some purposes the better one. Its database is strongest in Europe, which makes it valuable for finding matches who are still in Norway—the relatives who never emigrated—rather than only fellow diaspora descendants. It also offers useful tools that AncestryDNA lacks, notably a chromosome browser for examining exactly how you share DNA with a match, and—valuably—it accepts free uploads of raw DNA data from other tests. This makes MyHeritage an easy way to widen your search at little or no extra cost, as we detail in AncestryDNA vs MyHeritage for Norwegian ancestry.

23andMe and FamilyTreeDNA
Two other tests serve narrower purposes. 23andMe focuses on health and traits alongside ancestry; it is weaker for family-tree building, lacking tree integration, though its ethnicity breakdown interests some (see the caveat below). FamilyTreeDNA is the specialist for lineage testing—Y-DNA, which follows the strict paternal line, and mtDNA, the maternal line. For a Norwegian patronymic or farm-line question—testing whether two families share a common male ancestor—FamilyTreeDNA’s Y-DNA is the tool, complementing rather than replacing the autosomal tests above.
A note on 23andMe: the company filed for Chapter 11 bankruptcy in 2025, and a nonprofit founded by its former chief executive, the TTAM Research Institute, subsequently acquired its assets; it now operates on a nonprofit basis. The episode drew lawsuits and scrutiny over the privacy of customers’ genetic data. Your results would not be affected, but if the long-term custody of your genetic data matters to you, review the current privacy terms and know that you can request deletion of your data.
The Scandinavian ethnicity blur
Whichever test you choose, temper your expectations of the ethnicity estimate for Norway. Norwegian ancestry overlaps heavily with that of Norway’s Scandinavian neighbours, so tests struggle to separate Norwegian from the broader Scandinavian population, and typically report a broad region rather than a precise “Norwegian” figure. This is normal and not an error, and it means the ethnicity estimate is best read as interesting background rather than precise fact. We explain how to interpret it in understanding Norwegian DNA ethnicity results. The matches, not the percentages, are where the real genealogical value lies.
DNA does not equal citizenship
One honest caution, since the two are often confused: a DNA test showing Norwegian ancestry gives you no claim to Norwegian citizenship. Norwegian citizenship is a matter of nationality law—descent from a citizen parent, or naturalisation—and no ethnicity estimate or genetic result bears on it, as explained in our honest citizenship guide. A DNA test is a tool for family history and connection, not a document of nationality. Enjoy it for what it genuinely offers—cousins, confirmation and insight—without expecting it to open a legal door it cannot.
Our recommendation
For most people researching Norwegian ancestry, the sensible strategy is to test with AncestryDNA, for its unrivalled database and the best chance of finding diaspora cousins, then upload your raw data free to MyHeritage to reach European and still-in-Norway matches as well. Add FamilyTreeDNA’s Y-DNA if you have a specific paternal-line question. Above all, use whatever DNA reveals in concert with Norway’s free records, as we show in connecting DNA to Norwegian records—that combination, not any test alone, is what builds a real Norwegian family history.
