Hi and welcome. Sorry for the late reply but with the changes to Ancestry and new work hours it sometimes makes it to difficult to research during the week. When was Giuseppe born? Do you know where in Reggio he came from? The city or the province?
You say you're stuck but I'm not clear on what you're looking for - are you trying to locate records in Italy or the US? I always suggest that you start with what you know and work backwards. No matter how simple or tedious this seems it's an important step as it offers clues that you may otherwise miss. Write everything down using a software program (such as Family Tree Maker or Legacy) or using charts (forms can be downloaded here www.ancestry.ca/download/charts).
Hopefully we'll be able to help you out.
