Time to Most Recent Common Ancestor (TMRCA)

The FAIRBAIRN DNA pages have been updated to include more data on the more recent participants, primarily to include missing links to their family trees, and Genetic Distance to their matches, along with a revamp to a few of the dna signature charts.
This latter are where we attempt to combine paper trails and dna information to surmise where/how connected families MAY actually link up. Completely subjective!

The most overdue update (Lineage 1, haplogroup I1 only) however was to include new Genetic Distance and TMRCA tables according to complete theory, compared to the above, "by eye" and judgement.
The program used for those is that found from the ISOGG  pages - Dean McGEE's Y-DNA Comparison Utility  updated for 111 marker comparisons.
These can be found on the Summary Discussion pages.
The preliminary Jul 2009 tables have been left there to show us how far we've come - we even now feature in the list of those with 50 or more participants on the World Families Network pages (where the summary dna pages are hosted).

Several more broken links have been attended to over assorted connected pages (Summary pedigrees aka Patriarchs page, summary results, supplementary dna information, this blog). Would be good to think that the background rationalisation that has been going on for some months now is near completion, but somehow there's always "just one more thing" to attend to.

GD/TMRCA overall and Ralphs

Thought it was time to update the Discussion page with the current overall summaries of the Genetic Distance (GD) and Time to Most Recent Common Ancestor (TMRCA) results. There never seems to be a time when all results are in, so some partial results are shown, Doug at 12 markers and Tom at 37, more to follow. (Only the overall tables have been updated, not those for the split of Lineage 1 into clumps 1 and 2.)

Also expanded the stub for the Patriarchs page for Ralph & Helen (CROW) FAIRBAIRN.
A participant for this lineage is required.
NB the Ralph born Coldstream 1848 may have married an Elizabeth and lived in Heaton, Newcastle on Tyne, Northumberland. If so, sons George and James may have descendants able to contribute to the overall picture of the Borders FAIRBAIRN families.

New results - and yes, another match

The Scottish Borders have moved south as well as across the pond.
To date the matching dna signatures have been from participants able to trace their lineage back to the Scottish side of the Borders, most of whom had family who emigrated to Canada and the States.

The latest set of results, also from a descendant in the States, is from a family whose paper trail ends in Sunderland, Durham.
This is one side of the reported "cousins" triangle. Only 12 markers in so far (Joe, F-10)

Results chart updated.

Also check out the Discussion pages as they now have some tables for Lineage 1 Time to Most Recent Common Ancestor (TMRCA), and Genetic Distance (GD).
