Austin,
Thats the 'fun' of genealogy, solving the puzzle to figure out which person is which. The record I posted above only matched the birthdate you had given on her profile, but there are many Rosa Cianos, so you have to piece the puzzle pieces together to include all the facts.
Since the parent names on the death record don't match the birth record that matches the birthdate, it is likely that is not the correct person. If the immigration record can be shown to be her, then it narrows down the area to Montefusco Avellino.
Not all records are online, more get added all the time. However, Europe suffered many wars, and records were lost in fires/mold, etc. Just keep putting the pieces together.
