neither of your parents siblings had children?
Discussion
No. They have few siblings and none of those few had children. There is one aunt I’ve never met that I don’t think married but I’m not 100% sure. So I have no known first cousins and probably no first cousins period.
In the west, family size is shrinking.
My wife and I have dozens of first cousins each. Our children have exactly 12 first cousins, but their first cousins have anywhere from 9 to 18 first cousins.
Our grandchildren currently have zero first cousins.
Can you guess how many children we have?
It's just a guess without another given. If you ask for another clue, we can make it an easy SAT question.
