Steve,
bit of a long shot here, but I am trying to trace great great grandfather Antonio Bertolini - born in the Lucca region of Tuscany around 1805/1806. As a young man he became a plaster figure maker and took off to England - probably in the 1820's. He was in Hull, Norwich, where he got married and then in Holborn in London, where he lived to the grand old age of 80, passing away in 1885. I have all the England information - it's just the Italian part that I'm missing. There's some background information to be found here -
