A Z17911 STR Tree

Previously, I wrote a Blog on a STR Tree for Hartleys that were likely Z17911’s. In this Blog, I would like to look at others that have tested to be Z17911 or are likely Z17911 due to STR patterns. Since my last Blog, a lot has been going on in the little area of Z17911.

Z17911 in the L513 Tree

Z17911 is a small group under the L513 Group. L513 is a group under L21 which is a part of R1b. The L513 Tree is presently bursting at the seams:

One of the larger branches of L513 is S5668. That takes up about 2/3 of the lower left of the tree above. Here is a blowup of the Z16357 Branch of S5668.

At the time that I wrote the last blog, Merrick and Thomas were in the same location under an unnamed SNP. Now it has been named as BY11573. The placement of Merrick and Thomas below Z17911 was a result of my Big Y Test. Now Bennett has also taken a Big Y and found to be BY1157.

Enter Jared Smith on the Z17911 Scene

Jared Smith has been a large contributor on the Z17911 scene of late. He tested positive of Z17911 recently and has ordered a Big Y test. He is not to be confused with the Z16357 Smith above. Jared has developed an excellent web page called The R-Z16357 DNA Project. Jared has also created a discussion list for Z16357. Here is Jared’s updated version of the Z16357 Tree:

The part that I am most interested in is Z17911 and BY11573.

My First Attempt at a Z17911 STR Tree

First I took the 15 people listed as having STR results at the FTDNA L513 project. There are 6 that have tested positive for Z17911. There are an additional 9 that the administrator has put into a JM STR Cluster. The administrator figures that based on the STRs, they should also be Z17911’s. According to the administrator, Mike Walsh:

“You can see the “J” people 390=25,26 458=18,19 449=31 446=14. I would call this the “J” STR signature.”

I looked at the significant STRs for the 15 known or suspected Z17911’s and got this:

This was just for the first 37 tested STRs. I have the STR names at the top. I have the mode for L513, S5668 and Z17911. I tried to group the YDNA testers by patterns in their STR values. The GD is the Generational Distance. That means that the Phillips are closer to the Mode and Bullock and Bennett are furthest away. That would mean that Phillips should have the oldest pattern and Bennett the newest.

Here is the tree I built based on the above:

My intention was to have the oldest STR groups branching at the top and the newest branching nearer the bottom. I note that when I built my STR Tree for the Hartleys, I did it the opposite way.

The Problem with my first Z17911 STR tree

The tree was OK based on the way I did it. However, it did not account for one very important thing:

The STRs should account for the fact that the BY11573 SNP derives from Z17911. SNPs are the anchor and STRs may vary. Maurice Gleeson has promoted this type of analysis. In the old days, there were not as many SNPs. Now, due to Big Y type testing, there has been a tsunami of SNPs and it is now possible to incorporate them into STR analysis. When I added the SNPs to my STR chart, I noticed something interesting:

It took a while to see it, but I saw that all the BY11573 men had 13 or more for DYS439. All those who were Z17911 and not positive for BY11573 had a DYS439 of 12. Then I decided to sort my chart by DYS439:

Next I changed the DYS439 Mode for Z17911 from 13 to 12. This created a new oldest line of Gilroy. If DYS439 is the break between Z17911 and BY11573, then Phillips is now in the older, more signature BY11573. The results of a pending Phillips Big Y test will tell us for sure soon whether Phillips is BY11573 positive or not.

More SNP Structure

Jared Smith built a moreĀ  detailed SNP tree here based on recent testing information:

Here is the Z17911 part I’m interested in:

I would expect that the STR tree would follow the SNP tree. Here is a simple SNP/STR Tree with a few signature STRs that I have added in on the left top and bottom:

What if DYS439 = 12 is Z17911 and DYS329 = 13 is BY11573?

The Z17911’s I’m talking about are negative for the SNP below of BY11573. Until more testing comes in, that is the out on a tree limb assumption I’m making. Based on that and some other Hartleys that have had the YDNA tested, here is a spreadsheet for Z179111 positive and BY11573 negative people.

This Chart does not show DYS439 as these are all of the above have a value of 12. In the Chart above, I note a Gilroy/Goff/Smith signature of DYS391 = 11 and DYS576 = 16. That leaves the Hartley signature as DYS391 = 10 and DYS576 = 17, 18. I went back to the older S5668 Mode to get a feel for the overall direction of the STR mutations.

Z17911 STR Tree

Here is the tree I drew from the above STRs.

I tried to learn how to make these trees using two different methods, so it gets a bit confusing. In this method, only two lines are allowed to come out of each box. I like that method, but it required me to put in a Hartley Ancestor box under the West Yorkshire Hartley Ancestor box. On the bottom line, Gilroy probably has the oldest Z17911 signature. The Hartleys on the right have the newest signatures. Actually Wm. Hartley going up has the most STR changes (7), so I suppose he would have the most recent STR signature. Jared Smith has noted that I am positive for the SNP A11130, so it will be interesting to see if this is a defining Hartley Family SNP or not. Above I made a guess on the West Yorkshire and Lancashire Hartley split based on the knowledge that one of the Hartleys has West Yorkshire ancestors and that I on the bottom right have Lancashire Hartley ancestors.

Some BY11573 Patterns

I’m not ready to build a BY11573 Tree yet. However, I did note some BY11573 patterns.

Interestingly, most of the places where I found patterns were on the BY11573 positive people shown in darker blue above. If I were to draw a 37 STR BY11573 Tree at this time, it would just include those above highlighted in blue. The actual list of names was taken from Jared’s website and includes other names.

Next Steps

Next we wait for pending tests to come in and others who may decide to test. We are also awaiting analysis of the Bennett Big Y test from Alex Williamson at the L513 Page of the Big Tree.
