You are a Great uncle to your nieces child
If her child marries & has a child - you are it’s Gt Gt uncle

Use the same formula as for grandparents/great grandparents etc

[Duck]

Thank you Carole

If it is the same formula as for grandparents/great grandparents, would that not make you a granduncle/great granduncle

I think it depends on the custom of the country!      
Great in some Grand in others.
 I had never heard the expression Grand Uncle before joining RC.

I’ve never heard it all.  Only ever Great uncle or Great aunt

There was a thread on this a few years ago:

Great uncle, your nieces child, and great great uncle for your nieces grandchild.

If you had lived 300 years ago and left a will you would likely have said "cosen". Such as "To my cosen Elizabeth Smith ten pounds, and my cosen Hannah Bloggs ten pounds, and I give to the poor of the parish fifty pounds".

Or just kinsman / kinswoman - leaving us all guessing

I think you will find the Americans say grand uncle whereas we say great uncle. So it depends which country you are referring to.
