I am, on my mother's side, a descendant of the Tournour-Viron family and of the Tournour family of Gravere, Italy. I have a Rosina Tournour-Viron, daughter of Giuseppe and Virginia Malengo, b. about 1897 and removed to the US about 1913.This apparently is not your Rosina according to your posting, but may be related. My mother's father was Michele Tournour-Viron (1877 - 1958) and her mother was Maria Teresa Tournour (1877 - 1926). Maria Teresa Tournour was a daughter of Giovanni Battista Tournour and Margherita Carbonero. I have a book, "il sogno nella valigia" by Giorgio Jannon which was given to me by Rita Morello, a niece of Rosina, when we visited Gravere in 1996.Rita's husband is Franco Jannon, an uncle of Georgio Jannon.The title translates to "Dreams in a Valise" and the subject is stories and memories of emigrants from the Valley of Susa in the late 1800s and early 1900s.Although it is written in Italian, I believe I have seen the name of Tonietto in it.
