where come the last name Fasanando from

The surname Fasanando appears to be most common in Peru , especially in the San Martín region, and public surname databases do not list a single clear meaning for it. One Spanish-language source describes it as a very old surname in Tarapoto and says it was considered “netamente indígena” (indigenous), while another source suggests a possible Italian-style origin, but that claim is less certain.

What the records suggest

• Peru is the main center of the surname today, with about 5,085 bearers listed in one database.

• In Peru, it is especially concentrated in San Martín , then Loreto and Lima.

• A local-history source says the surname was described as an indigenous family name in Tarapoto.

• Another site proposes an Italian connection, but it does not provide strong supporting evidence.

Most likely answer

The safest answer is that Fasanando is probably a surname with Peruvian Indigenous or regional Amazonian roots , based on where it is concentrated and the historical note about Tarapoto. The exact etymology is still unclear, so any non-Peruvian origin theory should be treated cautiously.

Tiny note on spelling

There is also a similar surname spelling, Fazanando , that appears in Peru as well, so some family records may have spelling variation over time.

TL;DR: Fasanando is most strongly associated with Peru , and the best- supported historical clue points to an indigenous/regional origin , not a clearly documented European one.
