Afonso was an Amerindian leader who converted

Chief Tibiriçá baptized as Martim Afonso was an Amerindian leader who converted to Christianity under the auspices of José de Anchieta. He led the Tupiniquim people of Piratininga and other tribes. His daughter, Bartira, took the name Isabel and married a Portuguese man named João Ramalho. After his conversion to Christianity he became a strategic ally and protector of the Jesuits and the Portuguese; his name appears on letters to Saint Ignatius of Loyola and King João III of Portugal. Tibiriçá chose to side with the Jesuits and against his own brother Piquerobi with help of his nephew and his son-in-law João Ramalho. His granddaughters and their descendants married Portuguese noblemen that led the colonization of São Paulo under Martim Afonso de Sousa, including Jorge Ferreira, Domingos Luiz, and Tristão de Oliveira, son of capitão-mor Antonio de Oliveira and Genebra Leitão de Vasconcelos, both of important noble families.

Arthur Quintal was a Pitcairn Islander who served as the island's second magistrate from 1840 to 1841. Quintal was the son of Matthew Quintal, the bounty mutineer, and his wife Tevarua. The elder Quintal was killed with a hatchet in 1799. Arthur appears to have inherited some of his father's bad temper; he allegedly treated his sister Jane 'so harshly' she left the island and never returned. Quintal also allegedly made a pact with his best friend Daniel McCoy, to take each other's sister as a wife. Quintal married Catherine McCoy, and they had 9 children, including Arthur Quintal II, who also became magistrate. After Catherine's death in 1831, Arthur married Mary Christian and had a further 5 children. He succeeded his half brother as magistrate, and was succeeded by his brother-in-law. Quintal died on Norfolk Island in 1873.
