Isabel Martínez de Perón
María Estela Martínez Cartas de Perón (born 4 February 1931), better known as Isabel Martínez de Perón () or Isabel Perón, served as the 42nd President of Argentina from 1974 to 1976. She was the third wife of President Juan Perón. During her husband's third term as president from 1973 to 1974, Isabel served as both vice president and First Lady. Following her husband's death in office in 1974, Isabel served as president of Argentina from 1 July 1974 to 24 March 1976, when the military took over the government and placed her under house arrest for five years, before exiling her to Spain in 1981. She holds the distinction of having been the first woman to have had the title of "President", as opposed to a queen or prime minister.
María Estrada
Luisa Campuzano, in the fullest discussion of the problem, concluded that the sources support each other, and provide a consistent factual and psychological portrait, but other historians have been more cautious, suggesting that María de Estrada's military prowess may be a literary fiction, and inferring that she arrived in the New World too late to be the castaway rescued in 1513. A later date for her arrival in the Americas would imply that María de Estrada was Sanchéz Farfán's second wife, a different woman from the castaway he had married in Cuba, although the sources providing these dates seem to be unaware of his earlier marriage.
