John & Kathy:
There's a nice page on Wikipedia that gives some biographical information on Gian Galeazzo Ciano: http://en.wikipedia.org/wiki/Ciano
I think it's worth reading, and there's a photo of him as well. There is also another page that describes his father in some detail, and a photo on that page as well, but you have to go to the Italian language Wikipedia site to get to it.
From these pages it seems that Gian Galeazzo Ciano was born 1903 in Livorno, the son of Constanzo Ciano, also born in Livorno, 1876. Do either of you know of connections between this family and the Cianos from the Formia area?
