Premise: Maria Severa Onofriana (July 26, 1820November 30, 1846), also known simply as A Severa, is regarded as the first fado singer to have risen to fame, attaining a near-mythical status after her death. Fado has been described as the Portuguese expression of 'the blues,' and fado roughly means fate.
Hypothesis: She used her middle name for her stage name while singing.
