Elvira f
Spanish: of Germanic (Visi-gothic) origin, very common in the Middle Ages and still in use today. The original form and meaning of the elements of which it is composed are far from certain (probably ali other, foreign + wēr true). The name was not used in the English-speaking world until the 19th century, when it was made familiar as the name of the long-suffering wife of Don Juan, both in Mozart's opera Don Giovanni (1789) and Byron's satirical epic poem Don Juan (1819–24).
