A DNA test can do two valuable things for a Scottish family history: connect you with living relatives—sometimes cousins still in Scotland—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. Scotland also has a distinctive DNA angle: the clan and surname Y-DNA projects. This hub explains which test to choose and why.
Which test, in one line
For most people with Scottish ancestry, AncestryDNA and MyHeritage are the two to consider first. AncestryDNA has the largest database—best for finding cousins, especially across the Scottish diaspora. MyHeritage is strong in Europe and accepts free uploads. For the distinctively Scottish work of testing a clan or surname line, FamilyTreeDNA and its Y-DNA projects are the specialist choice.
The main options
- AncestryDNA — biggest match database, best for diaspora cousins, integrated with trees and hints.
- MyHeritage — strong European reach, a chromosome browser, and free uploads from other tests.
- 23andMe — health-and-traits focus; weaker for tree-building, with real privacy considerations (below).
- FamilyTreeDNA — the specialist for Y-DNA and mtDNA, and home of the clan and surname projects.
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 Scottish DNA
Scottish results have their own character. Ethnicity estimates within the British Isles are broad and hard to pin down—Scottish, Irish, English and Welsh ancestry overlap heavily and are difficult to separate cleanly. Read the estimate as interesting rather than precise, lead with the records, and—for surname and clan questions—consider the Y-DNA projects that are a particular strength of Scottish genetic genealogy.
