Marcon family - help?!

[renathamarcon]

Ciao! My name is Renata and I'm from Brazil.
A few years ago I started searching about my family heritage. My grandparents (already dead) are italian, but I can't find a lot of "Marcon" members there in Italy.
Can you please help me? Is that a common lastname? A cousin told me that it could be Lebanese but I doubt, because like I said, my grandparents come from Italy to Brazil.
