I'm not sure if I've replied to you before but in case I haven't, hello.
My cousin's son went to Alvito a couple of years ago to trace the family. He came across my grandfather'shouse and he also got a copy of his birth certificate - he was christened Sante. I can't now remember the names of his parents (I have them written down at home but am at work at the moment).
Alvito is very small and nestles in the Abruzzo area just south-east of Rome. I'm sure that the families were all connected in some way.
My mother remembers that her father (Sante) had a brother who went to America and she thinks also a sister called Domenica(?). Grandad's father came to England with grandad and another brother but I don't remember his name.
I'm planning to take mum (who's 84 now) to Italy so that we can see for ourselves where her roots are and to look up some relatives who are somewhere in Rome.
