The offspring of my parents' siblings are called my cousins.
What would my offspring be called in relation to my cousins' offspring?
Are they second-cousins? Are they removed in any way?
I ask 'cos there will be some family gathering over the coming summer, and I know this question will come up.
Whilst I'm here, are my cousins' offspring MY first cousin once-removed?
Expert knowledge sought.
Thanks.
