Dear cugina: I found your answer with joy. I am from Argentina, and according with I know, our surnames is present in Brazil, Australia, Canada, USA and, of course, in my country.
I am very glad with the news that you has roots in Marano Marchesato. To me, it means that we have a common roots. Marano M. has less than 3 thousand of people.
I will find out if the names that you told me are in my tree.
At last, one advice: see the site of Maranesis: you coud find it if you search in Marano Marchesato in google or yahoo (I don't remember right now).
Excuse my English: I am a Spanish-speaking born. But I could understand English (or Italian).
My best wishes for you and family
Daniel Espesir, from Argentina
