By the middle of the 15th century, the first important settlers arrived on the island, such as João Valadão, Gonçalo Álvares Pamplona (founder of Arrochela), Manuel Borges da Costa (descendant of João Borges "The Older", one of the first inhabitants on the island) and João Álvares Homem (relative of Álvaro Martins Homem), founder of the city of Angra. One of João Valadão daughters married Martim Simão (later identified with the toponymy of the parish, for example "Pico de Matias Simão" or "Pico de Martim Simão").
