In "As Senhoras Infantas filhas de D. João VI", published in Lisbon in 1938, Ângelo Pereira quotes, on page 161, a letter from the infanta to her brother Dom Pedro, assuming her marriage had not been authorized (although nothing in Portugal's law required a cadet infanta to obtain royal permission to marry). The Dukes of Loulé have not, in the past, pressed any claim to the throne publicly, whereas the Portuguese government and media have accorded some indications of recognition to the claimant Duarte Pio as the dynasty's royal representative since the death of the controversial claimant Maria Pia of Saxe-Coburg and Gotha Braganza in 1995.
