Some of these pioneering family names include: Fonseca Costa, Mello, Dias, Ferreira, Ferraz, Gomes, Ribeiro del Prado, Dias Ramos, Carvalho, Franco de Moraes, Souza, Barros, Teixeira, Milk, Marques, Paiva, France, Pinto, Melchert, Barbosa and Bueno.

In 1880, documents record the arrival of Jerome Martins Coelho, grandson of Lord of Cocais, coming from the edge of Mata, Minas Gerais.

He acquired large amounts of land that reached the localities of Santa Maria da Serra, Torrinha, Brotas, and Two Streams.

The potential for tourism associated with this geological feature is indisputable, with walls up to 100 feet tall, beautiful waterfalls, and caves of sandstone and basalt.

Torrinha is part of the western Sao Paulo plateau, which includes the geotectonic unit called Paraná Basin, where accumulation of thick sedimentary masses and basaltic volcanic eruptions occurred in the Tertiary period (Cenozoic Age – between 70 and 12 million years).

This caused underground tectonic and erosive processes; hence the emerging festooned-scarp relief called "cuestas" (Spanish: Encuestas) arranged in arcs towards the Brazilian Highlands, which encompasses the "Torrinha" rock as well.

Savannah and broad-leaved tropical forest species still exist in small isolated areas, although they have been almost completely decimated due to agriculture and stock breeding.

The presence of numerous rock walls and slopes that sprang from the "cuestas", primarily an "embarrassment" for the settlers from the beginning of the 20th century, preserved this natural and important sanctuary treasure for biodiversity in the state of Sao Paulo.
