French ethnologist Paul Rivet had suggested that the Peba–Yaguan family had been divided into two branches, with Yameo in one branch, and Peba and Yagua in the other.[<span title="This claim needs references to reliable sources. (December 2023)">citation needed</span>] There is extremely little documentation of Yameo and Peba, both of which are now extinct, though the town Pebas on the Amazon River clearly takes its name from this group of people. The available documentation is largely due to the efforts of early Catholic missionaries, as summarized by Rivet.
