What is the correct terminology to describe a first cousins' child, second cousin maybe?

I believe they would be your first cousin once removed.

It’s so confusing! According to this site, a child of a cousin is a first cousin once removed. I just call them cousins.

Yes @Pied_Pfeffer the removed just means they are one generation removed from you.
But cousin is also acceptable

I’ve always called them second cousins. There’s about 30 years between my cousins and me, so all my second cousins (or first cousins once removed, if you want) are my age. It’s all so confusing.

And I think your child and your first cousin’s child would be second cousins? The “removed” thing refers to differences in generations and the first, second, third, etc. refers to people/cousins in the same generation, I think.

It is first cousin once removed. Second cousins would be in the same generation and the children of first cousins.

In our family they’re referred to as cousines, 2nd cousins where talking more specific, rarely do we say cousin once removed.

The first, second, third, etc cousin tells you how many generations they are from the siblings that started the line. The removed stuff tells you how many generations they are away from some other cousin.

I think.

Your first cousin’s child is your First cousin once removed.
Your son’s relationship with that person is Second cousin.

Thanks for solving that little mystery for me… it’s strange to get to the age of 50 and realise I don’t know the answer to that, the subject came up in conversation recently and for some unknown reason I suddenly wanted clarification…

Help! I thought second cousins were children of two first cousins!!!!

@lillycoyote and @janbb and everyone else who said the same thing are all correct. I’m not confused by this terminology for some reason and always end up being the family explainer when these questions come up (usually when cousins get together).

@ZEPHYRA Nothing we said contradicts that.

It confuses me. So I just dismiss it alltogether. It goes right along with the monkey’s uncle thing. So I just call them cousins..and even then only when explaining relationships to newcomers.

@Adagio The child of your first cousin is your “first cousin, once removed”. The words “once removed” mean that there is a difference of one generation. That is to say, your first cousin and you share the same grandparents. Your first cousin’s child is one generation further from your grandparents (his/her great-grandparents), thus the “once removed. Per your second question, your child has the same great-grandparents as your first cousin’s child, so that makes them “Second Cousins”.
