Maria Helena de Albuquerque, 1st Baroness of Oliveira Lima (Funchal, São Pedro, 1817 – Lisbon, 6 June 1909) was a Portuguese noblewoman.
She was the seventh of eight children of João Agostinho de Freitas Brito Figueiroa e Albuquerque (Funchal, Santa Maria Maior, 14 June 1793 - London, 27 October 1862), Successor in many Majorats, Colonel of Auxiliary Artillery, 372nd Commander of the Order of the Immaculate Conception of Vila Viçosa (14 April 1852), and wife (m. Machico, Porto da Cruz, 1811) Carlota Amália de Ornelas e Vasconcelos (Funchal, Santa Maria Maior, 2 June 1797 - Funchal, São Pedro, 15 October 1860), sister of the ...th Lord of the Majorat and 1st Baron of São Pedro.
She married three times. Her first husband, whom she had married in 1836, António Teixeira Dória, ...th Lord of the Majorat of ..., son of Francisco Teixeira Dória and wife (m. Funchal, Sé, 1798) Joana Margarida da Câmara, was a First Mate in a Navy corvette whose Commander was João Maria Ferreira do Amaral (Lisbon, Alcântara, 4 March 1803 - Macau, 22 August 1849). According to their descendant Augusto Martins Ferreira do Amaral, 3rd Baron of Oliveira Lima, Maria Helena cheated her first husband with her later second husband, and believes that a first son of her, during her first marriage, João Eduardo Teixeira Dória, an Artillery Officer, born in Lisbon, São Paulo, on 13 October 1841, who died unmarried and without issue, was already João Maria Ferreira do Amaral's son, for he had similar features. She separated from the First Mate, went on to live in a Nunnery Convent, and got again pregnant of the ship's Commander, although this baby was already baptized as son of João Maria Ferreira do Amaral and an unknown mother, in order not to be registered under the name of her first husband. In Lisbon, Santa Catarina, on 20 October 1849, almost two months after the incident in which he was killed and without knowing those news, in order to legitimize their son Francisco Joaquim Ferreira do Amaral and their daughter Joana Teresa de Albuquerque, Maria Helena de Albuquerque, then a widow, married the deceased by proxy, taking advantage of the fact that, early in that year, her first husband had also died.
