How to find out more about your tribe?

When i was a kid my mom told me that our family partially originates from the Caiquetío tribe, i was fascinated and asked a bunch of questions. Almost all my questions were answered, but some things still weren't clear to me as i was simply too young to understand.

Now i've excitedly looked it up on Wikipedia, just to find out that the tribe Caiquetíos has died. There's no one left and aside from Wikipedia, almost every site i try to read about them is behind a paywall.

I've seen a dictionary from the Arowak language translated to Dutch, only to find out it's from Suriname (so the same people, just not my tribe).

What are other ways i can find out more information about my tribe?
