My sicilian great-grandpa, Salvatore Catalano, lived in Pittsburgh from about 1892-1900. He operated a one-man fruit store out of his house. There was a Catanzaro family **SPAM** fruit there as well. I found a Pittsburgh history article that mentions the Catanazaro Building as an historic site, so they must have been a notable family. One of Salvatore's children (not my grandmother) married one of the Pittsburgh Catanzaro's.
By the way, how did the Angelo Del Bello WIkipedia article fare?
The Angelo Del Bello article did not fair well... actually I have found that wikipedia is extremely hypocritical. That is, even though I may have included some unnecessary supplemental information to help color the article, the main criticism was that I used an informal tone and that Angelo wasn't noteworthy enough. The hypocracy I have found is that a significant percentage of Wikipedia article do not follow there own guidelines, but the article on Angelo that offers so much is continually rejected.
My 2nd great grandfather, Antonio Rizzello, was from Cortale, Calabria. Any relation to your Rizzello's? He was born in 1890 and came to the US in 1908. I'm pretty sure his father's name was Pietro Antonio.
