Task: Question Answering
Input (English): Passage: A young American man arrives in Palermo by plane. A taxi driver at the airport immediately gets word to Frank Ginetta, who hides, armed with a gun, until he realizes that the visitor he's been warned about is actually his younger brother Vinnie.
Frank happily welcomes his brother and takes him home, catching up on old times. But his wife, Ida, reminds him that "they're going to send someone," suggesting that perhaps Vinnie is the one.
In a flashback, Frank recalls better times in New York City, beginning with Vinnie's homecoming from military service and subsequent marriage to Emma Bertolo. The father of the bride, Dominick Bertolo is a Mafia don, as is the groom's brother, Frank. And among those paying their respects as guests at the wedding are mob leaders like Egan, Rotherman and Levin, who are the equals of Frank and Dominick in the New York region's organized crime.
These capos within the Organization meet as a board to coordinate their business. The majority becomes increasingly unhappy with Frank's position, as he seems opposed to every new idea. Frank also dispenses justice on his own in the old Sicilian fashion, without seeking approval from the others. They, not being of Sicilian origin, are trying to leave behind the old traditional methods, such as when two of Frank's hit men kill a stool pigeon in the marshes and leave him tied to a chair with a canary stuffed in his mouth, as a warning to others who might talk too much.
Frank still fondly remembers his father, who also was a mafioso who was assassinated in a hit. Vinnie is more of a businessman, and takes sides with the other board members in ventures they intend to pursue without his brother. Frank resents this, striking Vinnie for defying him and insisting to the board that Vinnie will have no part in what they have planned. 
Question: What is the first name of the don's brother's wife?
Output (English): Emma.
