FAIRBAIRN Lineage 1 DNA analysis

Lineage 1 (Haplogroup I1) Intro:

With the availability of more advanced testing now being available - Next Generation Sequencing (NGS) - such as the SNP discovery BigY test offered by FTDNA, together with analysis at yFull.com, and individual SNP testing for those unlikely to fund a BigY test (which makes SNP packs superfluous) it is now possible to finely place an individual on the haplogroup tree of mankind.
As new branches of the tree are discovered your results get refined.

Our ideal for our I1 matching Fairbairn families is a yDNA67 STR test, followed by a BigY test (sometimes on special) also analysed at yFull.com

Contributions to this analysis are most welcome - as are donations to the project, as it would be fantastic to have at least one BigY test per sub branch.

Explanation of above table:

The above table shows the dna results for all of the I1 haplogroup FAIRBAIRNs and their matching "outliers".
Only those markers that differ within the group are shown, which, as at Jun 2012, consists of only 27 of the maximum of 111 tested, and many of those differences are unique to an individual rather than indicative of a branch.
Beside each participant's identifier, eg Earl (F-2), is the current sub lineage they are assigned to, followed by the forename (surname of wife) of their earliest paper trail ancestor.
The lineage assignments are from an amalgam of paper trails, genetic distances from other participants, and the clustering automatically generated from the result markers to create a Phylogenetic tree (see the Phylogram below).
As more results arrive, or as individuals upgrade their marker numbers, these assignments may change, and may differ between the DNA signature charts (manual linkages) and the phylogram (automatically generated linkages).

Defining groups

Of the markers shared by more than one line, we can now see that there are several decided patterns developing.

So, how would YOU create a lineage chart combining these families into one?

Markers signifying specific lines:

It is assumed that those markers differing from the mode and occurring only on one line, are indicative of that particular (sub) lineage.
From the above differences chart, which shows, as at Jun 2012, only 27 of 111 markers as differing over the sample, this applies to:
(The following has not yet been checked to see if still fully relevant as at Jun 2012)
447 = 21 and cdyb = 36 for F-8's line of Thomas & Elspeth (REDPATH)
464b = 12 for F-12's line of John A & Sarah (DAUGHTERTY)
641 = 10 for F-1's line of John,  son of Archibald and Janet (SCOTT)
576 = 18 and 449 = 29 for F-14's line of Archibald, son of Archibald and Janet (SCOTT)
413-a = 25 for F-6's line of George and Janet (MURRAY) FAIRBAIRN, presumed parents of James m. Helen (GOODFELLOW), with 534 = 19 being the sub-lineage of Tom (F-13)'s forbears
389-2 = 30 looks like defining the line of F-17's John & Jessie (JOHNSTONE) FAIRBAIRN.
460=11 for F-10's Robert & Elizabeth (TAYLOR) FAIRBAIRN (ignoring the 460 = 11 shown by William (F-12) as being a separate mutation).
As of Mar 2011, it is now possible that this 460=11 may date to an earlier family, as a third line has joined this group, that of John & Elizabeth (YULE) FAIRBAIRN.
572=10 for (F-35)(James & Christian (LEARMONTH) FAIRBAIRN)

and possibly CDYa=37 for the overall line of Earl (F-2) (John & Bessie (FLINT) FAIRBAIRN).

Genetic Distances (GD)

The GD link below will lag behind in updates as it has to be manually created from the result set, unlike the DNA Signature charts which are generated from the underlying database which drives these pages.
It will show you the Genetic Distances between any pair of participants, using the Infinite allele mutation model, which may differ from the values shown on any one individual's page.
This output has been selected primarily because for this Haplogroup our particpants are very obviously all connected, and FT DNA did once advise that counting each difference may overstate the differences between related people (or that's how I interpreted this).

Timeframes (TMRCA)

As for the GD table above, the TMRCA link below will lag behind in updates.
It will show you the time to most recent common ancestor between any pair of participants.
The settings used were the 75% probability level and the Infinite allele mutation model.
The 75% level was chosen because it seems to "fit" where the actual relationships are known.
