Hi- I'm attaching an old newspaper clipping from my Great Grandmothers passing. In it you will see the names Garbarino & Dondero. I don't know if they are related somehow to who you are looking for but how often do these two names come together? This clipping is from Wanaque (used to be Midvale), New Jersey, dated 1961.
My great grandfather, Siro Macchiavello, came from Genova & my great grandmother, Emelia Mapello, came from the Milan area.
Have a great day & happy hunting.
