Even in more modern times, the details of how a population of people came to be can get lost.

For instance, nobody actually knew where the Romani people actually came from until the 1800s or so, and even then, the theory of a migration out of India (specifically, the Punjab region) couldn't be proven until the advent of modern DNA science.

That's an excellent point, and exactly what I was trying to point out in my post.
