Looking for 78's by Rosina Gioiosa

I am looking for 78rpm recordings of a wonderful Sicilian soprano named Rosina Trubia Gioiosa. As far as I know, her recordings were from 1924 to the early 1930's though perhaps even later than that. She was mostly on the Brunswick label, purple, but also on an Italian label called Fonit. The one I have is from Milan, Italy. She was on some earlier labels but unsure of the names. I am looking for any recordings by her. Thanks much.
Duane.
