The son of Bráulio Tarquínio de Sousa Amaranto and Joana Oliveira de Sousa, Tarquínio was born in Rio de Janeiro on 7 September 1889. He finished his secondary studies and joined the Faculty of Legal and Social Sciences of Rio de Janeiro, where he graduated with a law degree in 1907, beginning his career in the Postal Office administration and later joining the Postal Service of Rio de Janeiro from 1914 to 1918.
