herne:hermione, does that mean that Zak and Charity are second cousins, once removed. And if Charity is the daughter of a cousin of Zak's cousin, what would the relationship be. (I know I'm indulging myself here, but I spent ages at the archives in Cape Town, trying to work out my fathers large, extended family and emerged with head reeling - it's something that has always fascinated me)
I don't think so. If she was the daughter of Zak's cousin, the relatives that they share would be Zak's grandparents, I think, and in that case he would be her uncle, because to him they'd be grandparents, but to her they're be great-grandparents. I'm not sure if there are any removals though.
If she was the daughter of Zak's brother, then we all know that he'd be her uncle. That one is pretty simple.
If Charity was the daughter of a cousin of Zak's cousin it gets more complicated. If they were all related by blood in some way, then they would be first cousins once removed, assuming that Zak's cousin's cousin was also Zak's cousin and they were of the same generation. If the cousin's cousin was removed from Zak, then add an additional removal to the child, by they stay the same degree of cousin. It's easiest to work out if you have a family tree drawn up, because then you can see who is related to who and what generation they are!
If they weren't related by blood, then they wouldn't be related at all, technically.
