It seems that under Z140 (perhaps Z58 for a wider umbrella) haplotypes can be so similar that matches who don't show up on STR lists could be way closer through SNP testing. It makes you question how legitimate certain STR matches could be, I know that some of my 67 marker matches are quite distant thanks to SNPs.
    My current Subclade of I-S10350 has a TMRCA of 1950 ybp according to YFull. 14 people including myself have tested positive for this SNP at ftdna. None of the other 13 people show up at 25, 37, 67, or 111 STR matches to me. A few of them show up at 12 markers. 8/13 are Big Y matches to me at ftdna. Based on 30 or less non-matching SNPs perhaps I-S10350 is around 1500 ybp. At 67 markers a couple of them have a genetic distance of 10 to me which is 3 more than the matching threshold. Four of my 67 marker matches (genetic distances 3,5,7,7) just purchased Big Y-500 this past sale so it will be interesting to see how that correlates to shared SNPs in a few months. Almost all of my STR matches currently only show up as I-M253.

    Could you give specifics about how your 67 marker matches have more distant SNPs than your current subclade? Iím very intrigued by this.

    Sure, within my 67 marker list there are individuals who fell in the 62, 64 range who have origins in areas where my ancestors are believed to have originated from. Naturally I suspected that we'd belong to the same branch of I1, turns out while we do belong to the same branch we are on separate twigs. At the I-Y3647 SNP level there are 3 confirmed branches, A14097, A13248 and L234 (YFull data on A14097 and A14094 is incomplete due to my tardiness, I am negative for everything but A14097). These three SNPs branch into a few other branches, majority of my 67 marker matches fall into those other branches, while my two closest Big Y matches belong to A14094/M4050, which is downstream from my position. It was bizarre at first considering I'd looked heavily at one of the matches because in the days that we were 37 markers only we had nearly identical haplotypes. My two Big Y matches aren't on my STR lists until I believe 12 markers. The calculated distance with SNPs is fairly old, so the 12 marker thing makes sense, but why I seem to have converged with the other haplotypes is interesting.

    It seems (at least) for the Y3647 branch of I1 the haplotypes are shared across the branches with a few steps of deviation here and there.

    Wow! Itís a bit disheartening to see you have 67 marker matches with genetic distances of 3 and 5 only match up with SNPs in the 1750-1850 ybp range. I am downstream of I-Z58 as well. I hope Convergence is not universal with I-Z58 because Iím hoping to make many subclade branches with my four 67 marker matches who are currently waiting for their Big Y-500 results. Hopefully, Convergence is not an issue with 111 markers. I have one match at 111 markers with a genetic distance of 5. Im hoping to share many of my 17 unnamed variants with him.

    I suppose it could be disheartening but I'm patient with this I guess. Actually my 2 Big Y matches who are on my "branch" are distant STR matches and only show up at 12 markers and they are downstream of me, which places us at 1750-1800 ybp. My 67 marker matches are made up of my known cousins and then unknowns who happen to be from sibling branches of mine. My closest STR matches are known cousins save for one individual from Northern Ireland with a similar surname (practically identical minus a patronymic). At the Y3647 part of the tree it seems to look like this for me at least:

    Y3647 (Y7198 at FTDNA)
    - A14097 (I suppose I could be A14097* in this case)
    -- A14094 (M4050 at FTDNA)
    - L234
    - A13248

    Here is the tree at FamilyTreeDNA:

    https://www.familytreedna.com/public...;name=I-A14097

    I have one 111 marker match and it is a GD of 0 with a known cousin. I'm hoping more come rolling in.

    The TIP calculations can be very misleading for a noob. At 67 markers genetic distance of 3 it says there is 100% chance of being related within 24 generations or around 792 ybp. At genetic distance of 5 itís 98.89% within 792 ybp. These percentages definitely donít apply to your SNP branches of 1750 ybp. One question I have about the TIP calculator at Ftdna is whether these percentages apply to people with different surnames or if itís only for people with the same surname?

    Just got my full MTDNA results in.

    I am T2c1-t146!

    I will have a look around and join any projects that are appropriate.

    Well, I am now all tested out..

    Cheers, Ade.

    Here is the new revised chart at Y Full where I am now placed at I BY34647. The clade is estimated at forming around 1,950 years ago. My partner tester there is another Stevenson, and the MRCA is estimated at around 300 years ago. Sadly at the moment we cannot establish a link.

    Cheers, Ade.
