    Y-STRs alone can fail catastrophically. Here is a well-documented case. These two men have a GD of only 6 on 67 markers, as listed by the Y-DNA Matches page. Of the 54 slower markers, they differ only on DYS446.

    Ysearch N2997, kit N28490, of Poland, has tested L22- L287- L258- .

    Ysearch 982W3, kit 122603, of Finland, has tested L22+ L287+ L258+ .

    Thus, they are on opposite sides of the I1-L22 mutation, which is estimated to be 4100 years old.

    In fact, kit N28490 has now tested further:
    CTS6364+, S4795+, S4767-, YSC0001396-, CTS10028-, L258-, L287-, L22-

    BigY vs STR Stories

    Does anyone have a story or a link to a story about BigY being more valuable than STR markers in determining relationships between people whether there is a common surname or not?

    Today I watched a video DNA Lectures - Who Do You Think You Are on a presentation by John Cleary on how BigY has helped determine at what point in time the branching began with some people with different surnames but matched at the 67 marker level. Some of the branching is after 1300 CE, some before, and some around 500 CE. There is a significant difference to what they calculated the branching to be based on STR markers.

    This video shows that if enough people get the BigY that it can help more helpful that STRs with genealogy in the historical period and the period since surnames became widely used.

    The BigY portion of the video is at the 50m16s minute mark. https://youtu.be/O81G3No1SOY?t=50m16s

    The 67 marker match list portion of the video is at the 39m53s minute mark. https://youtu.be/O81G3No1SOY?t=39m53s

    I hope others are willing to share their stories.
