I have not found any records of baptism or marriage for my great-great-grandmother Luiggia Smiraglia, but I know her name and approximate birth year from her husband's and children's death records.  On her husband's canonical (church) death record, her name is given in Latin, as Aloysia.  His civil record gives his wife's name in Italian, Luiggia.  Her surname is given on her husband's death record as Smiraglia, and on the death record of her daughter Maria Burgio as Miraglia.
