You come across the term a lot in old genealogy books. For instance in "The History and Genealogy of the Prentice, Or Prentiss Family" (from 1883) contains:
> All his immediate family, himself, wives, and children, are dead.

I think it may have started in the late 1800s at the earliest. I would need a bit more evidence to be convinced that your model of individual to nuclear to extended etc has been a thing longer than a few centuries, vs the vast majority of human life experience being in nomadic hunter-gathering, villages, farmland, and walled city-states. We just had clans which were all our family. A fellow villager wasn't much different than a cousin. The individual and nuclear family, not so much a thing.
Probably you're focusing too much on the parent comment's mention of nuclear family. Even that, despite only being named a few decades ago, is likely to exist to some extent. Even in some ancient tribe or village, most people would favour their spouse (or equivalent) or child over a cousin or niece/nephew if some dispute formed. That hardly seems controversial.
in which they lived in families, extended families and tribes as the primary units. I didn't understand your argument at all.
I suspect you're actually talking about the current western/american conception of family (fair!) but it doesn't make sense to ignore this obvious miscommunication.
