Hi there,
My wife and I are distant relations (if you go back 7 or 8 generations). I'm going to try and explain this the best I can:
Example
William and Hannah Smith have two children:
Jacob and Emily Jones have two children:
In my wife's tree John Smith marries Ann Jones, and in my tree Thomas Jones marries Jane Smith. So both of our ancestral lines converge at that point and we share the same parents, grandparents, great-grandparents from then on out.
Is there a genealogical term for this? if not, what term would you use to describe it?
-
I always thought if two siblings married two siblings and both couples had children
That the children of the two couples were Cousins Germaine/German. As they are doubly connected first cousins.
But all the definitions I can find for Cousins German just has ordinary 1st cousins.
But I’ve seen it noted in the way I describe on an old legal document where they were trying to work out inheritance of an intestate estate.

I think the term is https://en.wikipedia.org/wiki/Pedigree_collapse (https://en.wikipedia.org/wiki/Pedigree_collapse).

Consanguinity ? :D

I could be wrong, but I think the correct term for the children of those marriages would be double first cousins. And genetically they would be as close as siblings, since they all share the same four grandparents.

I agree with Arthur - double first cousins:

Double first cousins.
I have found a few instances of 2 brothers marrying 2 sisters, as well as in Suffolk, 3 brothers marrying 3 sisters. Such instances can help though in getting back further. Such as John Bloggs wed Ellen Hamilton and in the same village a few years later Thomas Bloggs wed Elizabeth Hamilton. Although of course you need to double check to see if it is actually 2 brothers marrying 2 sisters.

Thanks all. Double first cousins it is.
It's a brother from side X marrying a sister from side Y, then the opposite, a sister from side X marrying a brother from side Y :)
I confuse myself trying to explain it!

Twin brothers marrying twin sisters. Neither sets identical.
