what is this couples relationship?

    My logical head is having trouble! - I've revisited one of my trees as I had a DNA match and now I've noticed some close marrying. Tbh it feels to close but probably not on the list on consanguinity. I'm struggling to work out how the final couple's relationship would be described - it feels like double 1st cousins if that is such a thing? I'll try and explain:

    Ann and William are brother and sister.
    Ann has son Horace. William has daughter Emma.

    David and Sarah Smith are brother and sister.

    Emma marries David. Horace marries Sarah.
    Horace and Sarah have son George. Emma and David have daughter Clare.

    George and Clare marry. What would best describe their relationship? (apart from married! :))

    Any suggestions much appreciated.

    They would be 1st cousins and 2nd cousins: 1st cousins because his mother and her father are siblings, and 2nd cousins because his father and her mother are 1st cousins.

    They wouldn't be double 1st cousins. That's when a pair of siblings marry another pair of siblings. The offspring of each couple would then be double 1st cousins, i.e. 1st cousins on both parents' sides.

    All marriages between persons who share an ancestor are consanguineous: whether they are legal or not depends on where, when and how close the relationship is. At one point the Catholic church had a prohibition against marriages to anyone closer than a 7th cousin. Even now the marriage described above would require a dispensation if one or both were Catholics.
