Jen, Tongue in cheek - yes - INCEST! It occurs regularly, and there are some relatives I am related too in a least three different ways. The most confusing example I found (not in my family as it happens). Was a Brother X & Sister Y marring a Siblings. Sister A & Brother B. Both had children, who would have been cousins twice over and Genetically identical. Brother X died, and Sister A died. Sister Y then married her Brother in Law B and had children, who were cousins & stepbrothers and sisters too the previous issue of their parents. They all had common Grandparents. Little regard was paid to Cannon Law, and the prohibited degrees of marriage it would appear.

I have a distant distant cousin, who appears to have a link with my tree on both sides of the family (VIAboth my grandmothers, then earlier via the male lines). Must be quite common, but my question is this: - Is there a term for this type of double relationship ?
