Connection Issues? Re: Upcoming BAM Submissions Request Drive for YDNA Warehouse
Hi again! Thanks for all the interest as a flash mob. You'll be seeing some sluggishness as the overgrown cell phone that hosts the site tries to keep up with you all accessing the new Study. I'm adding a cache in front of the pain point and responsiveness will improve loading the Member List. James Kane

Nature article - High-resolution genomic history of early medieval Europe
3
Published 01 January 2025.... High-resolution genomic history of early medieval Europe Abstract Many known and unknown historical events have remained below detection thresholds of genetic studies because subtle ancestry changes are challenging to reconstruct. Methods based on shared haplotypes1,2 and rare variants3,4 improve power but are not explicitly temporal and have not been possible to adopt in unbiased ancestry models. Here we develop Twigstats, an approach of time-stratified ancestry analysis that can improve statistical power by an order of magnitude by focusing on coalescences in recent times, while remaining unbiased by population-specific drift. We apply this framework to 1,556 available ancient whole genomes from Europe in the historical period. We are able to model individual-level ancestry using preceding genomes to provide high resolution. During the first half of the first millennium CE, we observe at least two different streams of Scandinavian-related ancestry expanding across western, central and eastern Europe. By contrast, during the second half of the first millennium CE, ancestry patterns suggest the regional disappearance or substantial admixture of these ancestries. In Scandinavia, we document a major ancestry influx by approximately 800 CE, when a large proportion of Viking Age individuals carried ancestry from groups related to central Europe not seen in individuals from the early Iron Age. Our findings suggest that time-stratified ancestry analysis can provide a higher-resolution lens for genetic history. https://www.nature.com/articles/s41586-024-08275-2

Is your EKA information accurate?
42
Dear all, I've begun to look again in earnest at the phylogeography of R-U106. To begin that, I've started some ground-work. A new PDF on my website details the current status of phylogeography and assesses the availability of information. Family matters will likely keep me from this for a while over Christmas, but I have almost completed an analysis of ancient DNA and how it charts the spread of R-U106 as well that I will append to it when I can. The take-home message from this document is to make sure your earliest-known ancestor information is up to date. To find this, log into your account, go to your name in the top right, and choose Account Settings. Click on the "Genealogy" tab, then the "Earliest known ancestors" tab below it. You should have a series of text boxes for your paternal ancestor with three pieces of information: a name and birth/death date, a country of origin, and a location. R-U106 has 70,626 modern descendants. Of those, 9126 (13%) are in our project (though many of the rest are recent Family Finder additions). Of these, 5805 have stated that their ancestry comes from a specific European country. Of these, 4696 have also given either a identified origin along with the name of their ancestor or a latitude/longitude. Of these, 41% do not match each other. In most cases, this is testers given an earliest-known ancestor in America and a country of origin in the British Isles. This means that we only have complete and fully correct data for 20% of our members. So: Please make sure your earliest-known ancestry is up to date and as accurate as possible (especially including specific locations). Please ensure all three boxes are complete and that the information matches between them. Please use modern country boundaries where possible (e.g. if your ancestor was from the Austro-Hungarian empire, don't put Austria or Hungary down unless your ancestor came from within their modern boundaries). Please don't quote a European country of origin unless you have good reason to believe it's true. Surnames alone aren't necessarily useful: as we've found out, just because you're a Johnson doesn't mean you weren't originally a Johannsson. Neither is the fact your ancestor was born in a British colony. If you do have good reason to believe your ancestry comes from Europe but can't prove it, briefly say why in the first textbox (e.g. emigrated from Bristol) and update the latitude/longitude to that location. The more complete you can make this information, the better. The situation is not dire - we can still make reasonable predictions from the 20% of correct data and reasonable assumptions about the 29% of mis-matching data. However, it would be really helpful to have more of this information believable, self-consistent and complete. By doing this, you will be able to improve our estimates of where our ancestors came from. If you speak to your matches, or if you run another project, please also encourage those testers to do the same. Best wishes, Iain.

An interesting German tool for surnames
This is an interesting tool for searching for surname spread across Germany. I used first 'Bucher' and then 'Buch' since -er was added to indicate an occupation. Geogen Geogen

R-Y49873 < was Re: Is your EKA information accurate?
Hi Michael, You asked about R-Y49873, which is part of R-Z159>S3251. I am busy looking at the upper echelons of R-U106 and its early migrations, though it is likely to be a while before I have a renewed idea of R-Z159 and its descendants as these are much later haplgroups. You can see previous analyses in message #5759. For R-Y49873 in particular, the few test results we have indicate that the haplogroup has probably been in modern Germany for the last 1000+ years. It's difficult to say much more than this without too much guesswork at this stage. Best wishes, Iain.

YDNA Warehouse Update
For informational disclosure to those who have added there data, I have implemented a more advanced Study (Project) system than the one discussed here in the past. All men who are test with SNPS at or below have been added to a Private R-U106 study of which only Investigators (Admins) have been added to demo the functionality. If any of the other current R1b-U106 or Subclade admins who have accounts in the warehouse want to preview this, let me know and I will add you to the Investigator list. Anyone with an account can access this from the Studies tab from their Manage Subject screen. There are Prefs settings that you can turn on or off the details on the Member list. Currently only members of the Study can see anything, but if it's made public it will behave more like my R1b-CTS4466 public study. If anyone has questions or feedback, this is a still in active development MVP feature. Thanks, James Kane

TMRCA of R-L151 and timing its growth
9
Dear all, I've updated the document I shared yesterday with a new section looking at the origins of R-L151 in relation to ancient DNA and its archaeological surroundings. Our (very!) old U106+ family member PNL001 was buried 2892 BC, and sets the minimum age for R-U106 and, by inference, R-L151. I've used the argument that we don't see any R-L151 basal clades that look like they come from outside the Corded Ware Culture (e.g. are found only in easternmost Europe or west Asia) and the need to have the R-ZZ11 (-> U152, DF27) spilt inside the Corded Ware Culture as limits to the oldest possible R-L151 date. From this, I get the TMRCA of R-L151 to be 3115 BC, with confidence intervals at 3222-3029 BC (68% c.i.), 3366-2972 BC (95% c.i.) and 3507-2937 BC (99.5% c.i.). These are much narrower than the dates Family Tree DNA gives (95% c.i. = 3754 - 2409 BC). Contrary to my previous expectations, this really means that R-L151 was probably reasonably well established before the CWC migrations happened, and that it might have been at about the split of R-P312, R-U106, R-S1194 and R-A8053 that the CWC migration begins. This young family of a few generations might still be small enough to travel together, or otherwise be small enough that any lines remaining where they came from were able to die out. I'm a little shaky on the archeaology here, since it's not my area of expertise. I'd appreciate any input that people have on the ideas behind it. Cheers, Iain.

Y DNA genetic distance reports
3
Will an administrator of this group make available to a tester the Y DNA genetic distance report for the tester? This report that is accessible to the administrators of this group. It shows matches for much higher genetic distance, 25 for Y DNA 67 and 40 for Y DNA 111 -- Kevin Terry

Change to DNA Listings
7
I saw on another group that the DNA spreadsheets have changed, and strangely those with kit numbers beginning with "B" have dropped off. As one who has been affected by this, does anyone have an idea of when it will be fixed? My SNPs still appear in each group of which I am a member, but my STRs no longer appear in the spreadsheets. Thanks, Ed

YDNA-Warehouse TMRCA Estimates
3
#age
Hello all, I have recently added myself to the YDNA-Warehouse and I noticed that some of the TMRCA dates seem more recent than the estimates listed on FTDNA. For example: R-Z159 shows 344 BCE - 816 CE; FTDNA estimates 1900 BCE. I¡¯m just trying to understand the reason for this discrepancy. Best regards, Herman

FGC11784 S6881 group and my kit.
3
Hello all, I had a kit number registered in the project under >FGC50431>S6881>FT5123>FGC42045>¡°446=14¡±>A11376) > for some amount of years but it disappeared off the results page a couple months back. I do suspect the reasoning, but just wanted to see if I could sort it out. I have a kit on FTDNA though only tested at the Y-DNA67 level, but had originally a confirmation of S6881 under Britainsdna (long gone) and now Livingdna. I'm afraid to say I forget who I had communicated with to join the project back on Yahoo but with this information they had used my Y-DNA67 info and the proof of S6881 to give me a rough plot further down the chain. With this info would anyone be able to suggest a kit to purchase to get me back on the project and confirm where I am in the tree? I'm unsure what I am beyond S6881 and the additional placement further down was likely to do with STR marker results, though I honestly know very little about the topic. If anyone could help that would be grand. Kind regards Alister

R-L47 Bronze Age Presence
3
Recently I have encountered a knowledge person claiming that R-L47 was not present in the Nordic Bronze Age cultures and only became part of the wider Germanic cultures in the Iron Age, possibly with the formation of the Jastorf culture. What are everyone¡¯s thoughts on this? I have looked pretty extensively through all the samples I could find and the earliest confirmed R-L47 sample seems to be a Roman era Saxon.

Project admin shake-up
8
Hi all, You'll have received an e-mail just now noting that Ewenn Gicquel has been added to the R1b-U106 project as a co-admin. Ewenn joins us primarily to help with automating a lot of the research work I'm trying to do (but don't have the time or skills to accomplish myself). I'm hoping that together we will be able to work on improved TMRCAs and more reliable origins than Globetrekker currently provides us with. This is one of several administrative changes that we are making. We are also retiring Zak Jones and Phil Chaddock from our admin pool - Zak and Phil have helped us with some of the manual data shovelling that our analysis work has required in the past. With the increased size of the project and volume of BigY testers, dealing with data manually is now not so much of an option, hence swapping Zak and Phil for Ewenn. Finally, Charles has also finally cajoled me into becoming a joint lead admin of the project with him, so I am now officially stepping up from co-admin to admin of the project. In practice, very little changes as a result: Charles will continue in the admin role he's had for 12 years, but I'll be giving him a bit of support with that. He's still grouping people, along with Connie and Kathy, and we still have gatekeeper Dan, Debbie, Vince and Ray helping out in various guises, and Robert who looks after R-FGC11674 are related groups in particular. We're hoping these changes will help this group approach the challenges in Y-DNA testing that will face us over the next few years. Here's to the future! Cheers, Iain.

R-FT334096
6
Hello, My FTDNA Y37 result is R-M269, which puts my ancestry in the steppe region. Using my autosomal test FTDNA placed me in the R-S18823 subgroup. My WGS at YFull placed me in subgroup R-A14198. The FTDNA database has multiple testers, so R-A14198 was split into multiple branches. My FTDNA 37 markers matches are positioned to R-FT334096. According to the SNP checker at YFull, my sample tested positive for all SNPs under R-FT334096 except the eponymous FT334096 SNP. What could be the explanation for this? Is YFull's SNP checker reliable? I wonder if I expand Y37 to BigY, what result would be obtained? Thank you in advance for your answers. Zsolt

R-Z18 project news
21
Dear all, I've been in touch with Peter Op den Velde Boots, who runs the Family Tree DNA R-Z18 project. This project has been dormant for a couple of years, but he is now investing time in it. His aim is to work through the backlog of membership and grouping during October, with a normal service running from November. Our two projects have similar aims, but differ in some approaches and opinions. While R-Z18 is part of our R-U106 family, we therefore encourage R-Z18 members to join the R-Z18 project as well as our own, in order to benefit from both sets of approaches, which each have their advantages. Best wishes, Iain.
