Which DNA test should I take?
Different DNA tests answer different family-history questions. The best choice depends on whether you want broad cousin matches, a direct male Jack surname-line test, or deeper surname-line placement.
Autosomal DNA
Autosomal DNA is the common cousin-matching test. It can help across many family lines, not just the direct Jack surname line, and works best when matched with a sourced family tree.
- AncestryDNA: useful because of its large matching database and linked-tree tools.
- MyHeritage: useful for international matches, tree tools, and comparison with researchers outside one platform.
Y-DNA
Y-DNA follows the direct male line and is most useful for Jack surname-line research where the tested person descends father-to-son from a Jack line.
- FamilyTreeDNA: the main practical platform for Y-DNA surname projects.
- Big Y: a deeper FamilyTreeDNA test for surname-line placement, branch discovery, and long-term comparison between related male lines.
GEDmatch
GEDmatch is an optional cross-platform comparison tool. It can be useful for comparing autosomal DNA results from different testing companies, but each person should read the privacy settings carefully and choose what suits them.
What Clan Jack does not collect
Clan Jack does not collect raw DNA files, passwords, private match lists, screenshots, health information, or full living-person trees. The DNA and Lineage Interest Register records research interests and consent choices only.
Recommended first DNA tests
- General Jack family history: build a sourced tree and use FamilySearch where a free shared-tree home is appropriate.
- DNA cousin matching: consider AncestryDNA or MyHeritage.
- Direct male Jack line: consider FamilyTreeDNA Y-DNA.
- Advanced surname-line placement: consider Big Y after the basic research question is clear.
DNA testing platforms and Scottish research resources
Clan Jack does not sell DNA tests or receive commission from these links. Before buying or uploading anything, check each site's current prices, shipping, privacy settings, terms, and data-use policies. DNA testing can also reveal unexpected family relationships, so it should be approached thoughtfully.
MyHeritage DNA
MyHeritage DNA can be useful as a second autosomal platform, especially for additional international matches, European links, and tree tools.

FamilyTreeDNA is the main practical platform for Y-DNA testing and surname projects. It is most useful for direct male Jack lines, where the Y chromosome follows the paternal line.

Scotland's People is one of the key official resources for Scottish family-history records. You normally need to register, and many record images require paid credits or current site payment terms. Always check the site before purchasing.
Visit Scotland's PeopleScotland's Places / Trove
Scotland's Places now points researchers toward Trove and related Scottish archival/place-based material. It is useful for place-based research, maps, tax records, Ordnance Survey Name Books, and local context. Some material may require use through Scotland's People or linked services.
Visit Scotland's Places / TroveDNA and records work together
DNA can point you toward useful family lines, but Scottish documentary research still matters. For Jack surname research, DNA clues should be checked against sources such as birth, marriage and death records, parish registers, wills, tax records, valuation records, maps, place-name material, and other local evidence.
Useful starting points include Scotland's People, Scotland's Places / Trove, the Jack Research Areas page, and the research downloads.
A careful research note
DNA evidence can support family-history research, but it does not replace documentary proof, whakapapa, or family context. Treat DNA as one form of evidence alongside records, oral history, place, time, and careful reasoning.
