Question for Geneology whizes- What is this relationship?

Question

OK...My Cousin recently came to visit...this relationship is pretty straight-forward..his Mom and My Dad are brother and Sister so HE is my first cousin..

By Help me out with the Rest...He Came with his Wife and Sons

What is the relationship between ME and His Kids...would we be called first cousins once removed, second cousins, etc..

Also, My Dad is My Cousins UNCLE, SO my dad said that he is the kid's GREAT uncle. That Sounds OK, but What are the KIDS to my DAD...My Dad said, I don't Know, They are my Nephews Kids!!!

Is there a term...Like are the kids called the Grand Nephews or something :) ???

Answer 1

Your Mom and his Dad are siblings - So he is your 1st cousin, correct.

You and his kids are 2nd cousins.

Your kids and his kids will be 3rd cousins.

The kids are your Dad's Great Nephew's, and your Dad is their Great Uncle.  

Answer 2

I do not know about the whole uncle thing,  I think it is great nephews, not grand nephews though.

But when it comes to your cousins, His KIDS are your first cousins once removed (because they are "only one person away" from being your first cousin, and then your kids and his kids are second cousins.  

Answer 3

your dad is there uncle,and you are there cousin.just that simple.no great uncle or grand nephews.

Answer 4

It is your second cousin, i am in the same situation, my mum is a great aunt to my cousins kid and my cousins kid is my second cousin
