Some of you will already know that all those who tested BigY will have been assigned their specific branch on the tree of mankind. Which branch is automatically updated as more tests are done and new branches created. BigY is the test that keeps on giving.
The recent Discover tool introduced by FamilyTreeDNA gives you information on your individual branch, along with a Time tree.
More recently FTDNA have also now provided the time tree information for a whole project, here's the Fairbairn project group time tree, a selection from which, for the Scottish Borders Fairbairn families is shown below.
yDNA branch snapshots over time can be found on the Guild of One Name Studies Fairbairn project webpages here.
The December 2022 snapshot of the different branches now tested, has been annotated with both the Discover timeframes at both the 95 and 68% certainty levels, and with the earliest known genealogy within the group (ie not necessarily the common ancestor for all in the branch).
You can select which branches to display by the project subgrouping assigned by the project admin.
The bulk of the Fairbairn BigY testers can be found under haplogroup I-BY21384
The earliest known ancestor shown on each branch here, is that the tester has entered on their test under their profile > Account Settings > Genealogy > Earliest Known Ancestors
Please check that you have completed this section - DO NOT GUESS. The key word here is known.
This information is also that shown on your public results on the y DNA results page.
If a padlock appears on the Discover group tree, the tester has chosen not to make their results public.
Check your settings under profile > Account Settings > Privacy and Sharing.
The recommended settings are Y-DNA match level > All Levels and
Match Preference summary to select all to be shared.
You can chose NOT to be notified of the smaller matches under Notification preferences.
There may be subsidised yDNA testing available for selected Fairbairn lines.
Contact the Fairbairn Surname DNA project administrator with the details of the direct male line concerned to enquire.
We recommend starting at y37 to test the water first and if results are as expected, do recommend saving the pennies, pooling funds with family members, and testing BigY to both contribute to your and science's knowledge of connections.
