Ok, I found some information about this rumor of 3 prequels to the GF Trilogy, and here is what I've found so far:

The Godfather Eposide One, "Rise Of The Boss", takes place in Italy. Antonio Andolini is 5 years old and is the fastest Donkey Racer in the town. He also has this gift of building donkey carts with his own hands. There is a faction in the same town that is looking to bring young Antonio to the dark side, under the Sith Lord Darth Ciccio.

In GF Episode 2 "The Italian Menace", we see a teen Antonio shrarpening his fighting skills with the Lupara. There are only a select few who are blessed with the ability of using the Lupara. Teen Antonio meets a pretty young girl from the village and begins courting her. He tells her of his dream to do good deeds for the poor people of the village by working for La Carabinieri. A Lupara Knight takes young Antonio under his wing and begins to train him in the ways of La Carabinieri. But Sith Lord Darth Ciccio has other plans for young Antonio. Slowly Sith Lord Ciccio brings Antonio to the dark side, but the episode ends with young Antonio having an inner battle between doing what is good, and what is evil.

Godfather Episode 3, "The Revenge Of La Casa Nostra", Antonio Andolini has married the young girl from the village. Meanwhile while working for La Carabinieri, he is secretly working for the Sith Lord Darth Ciccio, who has now changed his name to Don Ciccio. Antonio fathers a young boy named Paulo. However the dark side is taking over young Antonio's mind, and he is becoming stonger and stronger in the dark side. He begins to rise up under Sith Lord Don ( Darth) Ciccio, and together they form an alliance called La Cosa Nostra. Menawhile Antonio's wife becomes pregnant. A final conflict takes place between The Lupara Knight who trained young Antonio, and Antonio has the opportunity to kill The Lupara Knight, but his good side wins over and he does not follow through. Sith Lord Don Ciccio finds out that Antonio was weak in the dark side, so he has his Bounty Hunter find Antonio and The Bounty Hunter kills Antonio. The movie ends with Antonios wife giving birth to a baby boy, whom she names Vito. But the midwife informs her that there is a second child, a twin that she is ready to deliver, and it turns out to be another boy whom she names Emilio. Antonio's wife decides that she will keep Vito and his brother Paulo with her, but that it would be best if she hid the ther twin's identity from everyone. So she gives the twin son Emilio to the midwife, who takes the baby to America, and gives the child a loving home with a family that she knows who cannot rear children of their own. The family adopts baby Emilio and has his last name legally changed from Andolini to their own name....Barzini.
