All the above dates permit us to conclude that, ethnographically, the Yámassi were for the main part of Creek origin, but that some foreign admixture, either Kataba or Yuchi, had taken place, which will account for the presence of their local names of foreign origin. The Apalachian or Hitchiti branch of the Maskoki family must have also furnished elements to those Yámassi who were settled southwest of Savannah city, for that was the country in which the Apalachian branch was established.
