Genco Olive Oil

Is this a bit obscure? On Wikipedia, I can find just one mention of Genco, and it's in respect of The Godfather Part II: "Vito and his partners are becoming more and more successful, with the establishment of their business, "Genco Pura Olive Oil"." This appears to be in one of the flashbacks to Vito Corleone's youth.

For any more detail, you have to go to one of the 'fan' sites: The Godfather Wiki, for example, or Facebook.
