DNA Register
This page shows a public summary of the Clan Jack DNA and Lineage Interest Register. It helps show where Jack researchers are active, what kinds of DNA tests are being used, and which broad research areas are emerging.
No private names, email addresses, DNA results, raw DNA data, private match lists, or living-person family details are shown. Public reporting is anonymous only. The Register is strongest when more Jack descendants add their broad details.
Area labels are broad summaries only. A specific area is shown publicly only when at least two approved active entries fall in that bucket.
Autosomal DNA can help with broad cousin matching across all family lines. Y-DNA is most useful for direct male Jack-line surname questions. Big Y may help compare older male-line branches when the paper trail is strong.
Join the Register if you would like testing guidance recorded with your Jack-line details.
| Situation | How the Register may help |
|---|---|
| I have Jack ancestors but have not tested | The Register can guide testing choices. |
| I tested at AncestryDNA or MyHeritage | Your Jack-line details may help identify research clusters. |
| I am a direct male Jack-line descendant | You may be especially useful for Y-DNA. |
| I know my Jack line came from Scotland or Ulster | Broad area signals may help guide future research. |
| I want contact with a possible branch | Clan Jack can only make an introduction after consent from both sides. |
