I am searching for the names of the parents and other possible siblings of William Joseph, Henry Tancredie, and Otto (Torguato) Petrini/Petrin. Their Americanized surname was Petrin. Their surname before they immigrated might have been Petrini.
William Joseph was born in Switzerland in 1876; Henry in Venice, Italy, in 1877, and Otto in France, possibly Marseille, in 1879. Their parents might have been Bartholemew Petrini and Sabina/Regina Reff.
The brothers immigrated to the U.S. in 1900 and lived in Newark, New Jersey.
