An early Christmas present yesterday, two long awaited BigY results, one rather anxiously as we hoped that there was enough sample.
The impacted branches and surname projects are in the Recent changes list, mainly being the families of James SINTON of Abbotrule / Southdean, Roxburghshire (a second BigY result to refine his branch of the yDNA tree - see the SintonDNA project diary for specific links/info), and Joseph ROWE of Bere Ferrers, Devon (our first result for this branch, another to come).
As a result, the DNASurnames Haplogroup section has been republished, but not, as yet, the Lineages and analysis portion.
An earlier update for another of the I1 FAIRBAIRNs is included as well, but having only just finished yFull processing not yet been further analysed.

DNASurnames - Haplogroup tree update
With a set of new BigY results in from the last sale, revisions have been made to the Haplogroup trees on DNASurnames - mainly under Fairbairn and Dawe but one or two others.
Check out the Recent changes.
Please note the trees are by no means all haplogroups, just those relevant to people of interest.
They show a position on the tree, with the profiles for the haplogroups sometimes including links to eg yFull, the BigTree, Surname projects for more info.
"Children" shown on a profile page include either more recent SNPs down that branch of the tree, or a patriarch for a tester of interest's line.
Each branch is collapsible/expandable to aid showing the relevant bits of the tree.
For ease of navigation, you can click on a chart link on the profile page, or in the little blue pedigree symbol up against the name for an overview of "ancestors" and "children".
Have you bitten the bullet and upgraded a relevant person for your surname of interest to BigY?
The sale price until the end of December is $100 off, but FTDNA have thrown in an upgrade to yDNA111 from whatever yDNA markers you already have.
Coupon codes are available each week that may sometimes be valid for BigY in addition to this.
I may have some available for suitable candidates in the projects I admin, or am interested in.

Benefits of BigY and yFull
The Fairbairn surname DNA project has reaped the benefit of testing a group for BigY and having the results analysed at yFull.com.
http://fairbairnsall.blogspot.com/2017/05/update-for-i1-haplogroup-fairbairns.html
refers.
A new branch, I-Y32666, with an estimated TMRCA of 225 ybp, has been created under I-Y7277 on the I1 haplogroup tree.
Now all we have to do is convince a few more of the matching Fairbairn kits, or an Elliot or two, to similarly test, to see how far back from that the Fairbairns and their matching Elliots (a very small subset of that surname project) diverged, or were still together for that matter!

BigY "matches"
As a complete layperson when it comes to interpreting BigY matches, I rely on the people on the DNA forums, YFull.com, and the wonderful work of Alex Williamson and his BigTree (for R-P312 and sub branches). Wish there was an equivalent to Alex for I1-Z60!
This post is me thinking out loud as I explore why the yDNA67 group of matching RUNCIMANs are showing up in the BigY Match lists for the yDNA67 group of matching FAIRBAIRNs.
Back when both projects began individual SNP testing we learnt that both were I-Z60, so on the same branch back within recorded history.
They subsequently diverged.

Big Y – Matching
The Big Y – Results, Matching tab displays your Big Y matches. A person is considered a match if they have four or less differences in SNPs with you.

where
Known SNP Difference
Known SNP Difference
This column displays the number of known SNPs within your subclade that you do not share with the specified match. The following values are possible:
- 0 – Indicates that you share all known SNPs with the specified match.
- 1 – Indicates that there is one known SNP in the subclade that you do not share with the specified match.
- 2 – Indicates that there are two known SNPs in the subclade that you do not share with the specified match.
- 3 – Indicates that there are three known SNPs in the subclade that you do not share with the specified match.
- 4 – Indicates that there are four known SNPs in the subclade that you do not share with the specified match.
Subclade
A subclade is a subgrouping in the haplogroups of the human genetic trees. This may be either the Y-chromosome tree or the mitochondrial tree. Subclades are more specific to a location or population group than the major branches (haplogroups).
---
Which I suppose explains how come the newly tested FAIRBAIRNs are showing up in the already tested RUNCIMANs matches and vice versa if you take "your subclade" back far enough, although I'm not altogether sure I consider 4000+ years before present a "match". Perhaps I'm too used to working with atDNA these days!
Both surname groups were I-Z60 back when we were doing individual SNP testing to advance down the tree, formed 4300 ybp according to YFull.
But then the RUNCIMAN matches headed off down I-Z160 to their own newly created SNP I-Y22033 (YFull, formed 500 ybp).
We knew back at the individual SNP testing stage a while ago that the FAIRBAIRNs are I-Z140 (which YFull estimate as forming 4100 ybp)
A brief overview of some of this structure is available on DNASurnames under the I haplogroup chart which shows selected branches, the patriarch for the line, and the tested participants who agree to be so shown. Branches can be expanded or collapsed for a better overview by clicking on the + - symbols.
Looking at the latest set of FAIRBAIRN BigY results, 5 of the 6 RUNCIMAN tests show in their match list as having 4 SNP differences PR1457 Z140 Z141 PF3832, with one not showing Z140 in their list!
Shared novel variants range from 30 to 41 for the RUNCIMAN matches, compared with 57 and 61 for the two other tested FAIRBAIRN matches with zero known SNP differences.
An interesting exercise in timeframes.
yDNA matches don't tend to appear in Autosomal match lists
BigY matches don't seem to appear in yDNA STR matches (although for this one I have noted some exceptions).
Not at all sure what I've really learnt from here but it is fascinating watching the developments on the respective yDNA haplogroup trees at FTDNA, YFull and Alex's BigTree.

Republished
DNASurnames has been refreshed.
Main changes:
- any place names mentioned in a person's page should now have a dinky little icon after the place to take you to either Google Maps (all places) or OpenStreetView (those with lat/long only).
How accurate such links may be is open to exploration!
- a few additions to/refinements to placings on the Haplogroup Trees as people get results back from SNP or BigY testing, including subsequent YFull analysis
- another RUNCIMAN BigY result in (exact match to our first result, sharing 245 novel variants with his GD4 Y-STR match). One day the I-Z60* section will be analyzed further and have sub branches.
- ROWE pages revamped a tad to remove data more aptly viewed (and more easily updated) on the Summary WorldFamilyNetwork pages and to remove analyses done back in 2007/8 that are no longer relevant
- HENDERSON FamilyFinder data updated to include (some of) the results from the known descendants of Archibald & Margaret (McEWAN) HENDERSON using the wonderful new tool on GEDMatch.com - Shared Segment Traceability *.
If you haven't yet uploaded your atDNA raw data file(s) to GEDMatch.com, please consider doing so. It's a great site.

BigY/SNP packs
Those of you following Y-DNA trails towards male line surname matches have undoubtedly noticed the advent of BigY testing and the recent welcome addition of SNP pack offerings from FamilyTreeDNA.
I hope that you have all joined your relevant Y-DNA haplogroup project and followed the advice of the admins for these as to whether or not the SNP packs that have recently been offered to sort out the top levels of the haplogroup tree are relevant for your particular circumstances and existing test levels.
For those venturing forth into BigY, Roberta Estes has a useful blog post from last year:
http://dna-explained.com/category/novel-variants/
The RUNCIMAN project has recently ordered the first BigY test for its SNP testing guineapig and we await results with interest - keep an eye on the RUNCIMAN blog for the results.
The quest that got me into DNA testing in the first place was for my HENDERSON brickwall. BigY results are in, and we appear to still be stonewalled at S7361 down the R1b tree and awaiting a breakthrough match or a growing number of people sharing the same "novel variants" to create a new branch.
Autosomal testing is providing some intriguing leads in the meantime.
