One of them seems that you can see something of the Americas in him and in a somewhat undefined way, but the rest, if I found them in those worlds, I would never have thought they were South Americans.
Davi Alcolumbre has a very common, if not the most common, biotype in the north and northeast of Brazil, although his whole surname is totally unusual for Brazilians: David Samuel Alcolumbre Tobelem. The other one, Mr. Abraham Bragança de Vasconcellos Weintraub is known in Brazil only as Abraham Weintraub. He carries the surnames “Bragança de Vasconcellos”. I highlight that “Bragança” is one of the surnames that carries the royal family of Portugal and Brazil. He has a very common biotype in the rural areas of the Midwest and Southeast of Brazil. I would not hesitate to label him a “caboclo”. Caboclo is a mix where European ancestry predominates, but with significant percentages of Amerindian ancestry (more) and SSA (less).
