There were several Rosa Bevilacquas from Torriglia...Mine was born 10 Apr 1881. "My" Rosa's parents were: Giovanni Bevilacqua (1858) and Paola Rossi (1859) and she married first Luigi Mangini (born Torriglia Apr 1871) and after he died, Stefano Sciutto (Shutte) born Fonanagordia province, Genova 1867.
I also have the Traverso connection in my tree with Serifino/Serifinus/Giuseppe aka Michael and they married in NYC 22 Dec 1904. This Rosa's siblings were: Giovanni Battiste (1879), Giacomo (1880) my Rosa (1881), Rafael (1884) and Paolo (1888).
Paola Rossi had a sister, Maria (1857) who married Giovanni Battiste Bevilacqua (1855) and had at least 3 children: Palma, Maria and Rosa.
Other Rossi siblings: Andrea (Andrew) 1860, Luigi and Luigia (most likely twins) (1861). Hope this helps.
Cheers!
