Ancestry DNA Matches

    I'd already grouped all my matches - I have tried to split it into 8 GGP and some of these I've also identified the 2xGGP and 3xGGP. So some of my second and third cousins are in more than one group. Most of my paternal line I know exactly where the connection is, and the same for one of my mother's grandparents.
    Quite a few matches are flagged "common ancestor" so Ancestry has missed a trick by not using this information.

    I agree, they could use this information. However, in some cases the 'common ancestor' information is incorrect, so it's up to you to check it and label the person (or not) accordingly.

    They have just got round to me!
    I have just got the pop up

    I've just noticed that one of my Ancestry matches has the following statistics:


    Downgrading a 37cM segment to just 8cM seems quite drastic - I've never seen such a large percentage reduction (78%) before. Does anyone have a comparable example?

    That does seem a very drastic downgrading! I haven't come across anything so drastic amongst my matches, though I have one where a single-segment 35 cM match has been downgraded to 14 cM. This is for a documented 4th cousin 1x removed.
