Cuquio baptisms

I'm looking for the baptism of an illegitimate child that was probably
baptized in Cuquio around 1785 -1790. His name was Atanacio, son of
Felipa, and the last name might have not been given, or if given, it
was probably Peres, Rivera, Velasquez, or Gonzalez. Atanacio might
have been listed as Indio or mestizo.

It seems that the only available films are are for legitimate children
(e.g., "Bautismos 1772-1788" & "Bautismos 1789-1796").

Does anyone know illegitimate births were included in other Cuquio
church books, or perhaps went to another town for such a baptism?
