If you are still interested, I have some information. My grandfather Bartolo Martini and my Grandmother Rosa Rossi, both of Revo left in the 1890's to go to Pennsylvania. The Martini family has been traced to 1493 in Revo and the Rossi family to the 1600's. Our Martini supername is Lau and the Rossi name is either Perla or Sheck. There was so much intermarriage that there are other supernames somewhere. All of the listed names appear in my family. Bertoldi came in as a husband of Maria Martini, my grandfather's sister. Margie Martini Jones
