When was the first time the notion of relatives like cousins were used?

Question

As you all know almost every family has relatives(nephew, nice or cousins etc..) So i would like to know when was the first time the notion of relatives like cousins were used?

Answer 1

I suspect it's usage is so far back, close to the dawn of language, that's it's impossible to tell. Relationship words like you mention are common to every human language in existence.

Answer 2

yep
