In any case, they assigned me to I1a1/CTS6364/Z2336. Subsequently, I tested at 23andMe and their test drops me a few subclades further down, below I-L22 to I-L205.1 (I1a1b1a3 / L205.1/L939.1/S239.1).

    I was pleasantly surprised to see how far down 23andMe got me as I had been looking into testing further with Family Tree DNA and it was looking like $200 to get anything clearer than what LDNA assigned. I've got to say, though I left them for my last stop, I'm very impressed with 23andMe. And I paid $50 for that kit in a 2 for 1 deal!!

    One weird thing is that 23andMe says this L205.1 haplogroup is relatively common at 1 in 54 testers - how can that be possible? Even if the I haplogroup is 10% of US testers, I can't make sense of their estimate that L205.1 is 1.8% of 23andMe testers. I would have thought being this far down the tree there would be far fewer folks who are in this group. Of all the people who tested at FTDNA, there are only like 30 who are at this level or lower. Clearly, the 23andMe database is much bigger, but still...something doesn't seem to be adding up. Can anyone shed any light on this?

    My paternal line traces back to Northumberland, England and perhaps from there into Scotland - that's where I lose track of it. I would like to see if there are any family conclusions that can be drawn from this haplogroup. My current guess is Viking "visitors" hit the eastern coasts of Scotland, take a wife and eventually, a Scottish sounding surname, and Bob's your uncle! (or however you say Bob in Viking).

    Here's the breakdown of the relevant haplogroups at FTDNA, last time I checked. It's definitely a moving target:

    I-M170 (2,917 downstream branches)
    I-M253 (1,804)
    I-DF29 (1,750)
    I-Y2592 (782)
    I-CTS6364 (772)
    I-CTS10028 (635)
    I-S6346 (629)
    I-L22 (608)
    I-Z2338 (502)
    I-L205 (11)

    Possible downstream subclades:
    I-A1463 (10)
    I-A1465 (6)
    I-Y11821 (3)
    I-A5574 (2)
    I-A5572 (1)
    I-A14140
    I-A13863
    I-Y51401
    I-A10198 (1)
    I-A10201
    I-BY123303
    Yes, you likely have the V5 chip that 23andme tests on from about August 2017 onwards. JonikW and I had our 23andme tests when they were using the V4 chip - that one only tested M227, M72, L22 and P109 downstream of I1. So myself and JonikW just show as I-M253 because we're on a different branch. You would be I-L22 on the V4 chip. V5 expanded the coverage quite a bit - ArmandoR1b made a very helpful spreadsheet on what 23andme V5 covers.

    With regard to your questions about how 23andme determines how common your haplogroup is - you're right, it's a bit of a mess. Here's mine today - it says that I-M253 is extremely rare at 1 in 250000. That's clearly a mistake on how they are counting the numbers and probably not including subclades.

    Especially when I compare it with when I first got my results (and that seems a bit inflated).

    So however they are counting those numbers, there's something wrong. The only thing I can think as to why they are reporting you as "relatively common" is that L205 is known to be a recurrent SNP that occurs in several haplogroups - most often in I and Q, but also in others (see this from a search at YFull). Perhaps they are tracking just L205 as a single SNP rather than L205 in combination with the I1 SNPs. So I-L205, Q-L205, G-L205, R-205, etc all counted together. Not sure if that is what they are actually doing.

    If you're looking for some selective SNP testing to further investigate below I-L205, I'd highly recommend checking out YSEQ. There's a lot of flexible options for ordering, not very expensive, fast turnaround.

    Yes, for sure I'm V5...tested pretty recently. Do you have a link to the ArmandoR1b spreadsheet? I could search...

    Yeah, I just don't think those "percentage of testers" numbers actually mean anything. I'll email their science team and see if I can ferret anything out.

    I guess I never considered counting downstream markers from other groups; I mean, once I go down the I path I'm in a specific part of the phylo tree, nothing to do with Qs, Gs, Rs, right? I can't imagine why they'd count across different haplogroups.

    Thanks for the input on YSEQ. I have looked at their site and that's probably the direction I'll go to see if I can find anything more specific about my Viking forebears.
    Latest paper trail:
    Lancashire/Manchester - 21.9%; Northumberland/Durham/Scottish Borders - 15.6%; Scotland - 15.6%; Ireland - 15.6%; Mecklenburg-Schwerin - 12.5%; Somerset/Devon/Wales - 6.3%; Essex - 6.3%; Unknown - 6.3%

    Sure - ArmandoR1b made the spreadsheet available in one of the threads in the 23andme section which can be found here https://anthrogenica.com/showthread....-v5-Y-DNA-SNPs and in dropbox here https://www.dropbox.com/s/t8ojpasj08...blic.xlsx?dl=0 - L205 is included in the spreadsheet under the haplogroup Q SNPs (where it is also found), but you'll also likely show positive results for upstream SNPs that are part of I1 on your branch such as L22, Z2336 and son on.

    Yeah, I don't know either. It was just a thought that came to me after seeing L205 appear in several different haplogroups. Doesn't mean that they are actually doing that, purely speculation on my end. But for sure, there is something a bit wonky about how they are counting.
