  • X-match between two women

    Hi guys!

    My mother got a X-match female and they shares 37.3cM. Does anybody know how many generations ago can be the ancestor?

    Thanks in advance.

    Can you clarify whether they share 37cM on the X-chromosome, or 37cM in total across all the chromosomes?

      They only share cM, at one position, on X-Chromosome. But, my mother shares cM, on others chromosomes with a relative of them.

        If the 37cM was located on chr 1 to 22, it would sound like a 3rd to 4th cousin, but that's just a loose estimate.

        On the X, the amount of cM points back further in time, but the X estimate is even less reliable.

        So....maybe.....4th or 5th or 6th


        I have a bunch of confirmed, triangulated 4th to 5th cousins. We share anywhere from 13 to 60 cM on the X.
