Hi Richard,
I'm Fabio Viventi. I'm not sure, but I think that we met some years ago.
I live in Gualdo Tadino with my family. Are you Barbara's brother?
I don't know this site, it's beautiful!!
Now I will search about Giovanni Viventi, in order to know if we are relatives
Meantime you can contact me by email:
