Bilancia to Belancio

I am looking for information on a Vincent Bilancia, who may have been a brother of Gerardo/Girardo Bilancia.Gerardo/Girardo changed the spelling of his name to Belancio at some point in the early 1900's, but it was still spelled Bilancia when he was married Feb 6 1894 to Marie Chiosso.Vincent Bilancia was one of the witnesses, in Philadelphia.If you have any information on Vincent Bilancia or descendants (He was probably born around 1860's or 1870's and probably immigrated from Italy before 1894), please let me know.Thanks.
