William Alatriste/New York City Council

Here are four things you might not know about New York's Democratic Mayor Bill de Blasio, who will sit down with George Stephanopoulos Sunday on "This Week."

1] EARLY LIFE:

Bill de Blasio, New York's 109th mayor who was elected in a 2013 landslide, could have been Mayor Warren Wilhelm, Jr. had he not changed his name, adopting his mother's maiden name later in life. Coincidentally, the mayor was actually raised in Massachusetts like his predecessor Michael Bloomberg. And yes, that means New York's mayor is a big Red Sox fan.

2] EDUCATION:

The mayor, who stands 6-foot-5, graduated from New York University in 1983 and later attended Columbia University's School of International and Public Affairs.

3] FAMILY:

The mayor is married to Chirlane McCray, who is African American, and the couple have two children, Chiara and Dante. The mayor's son appeared in an ad for his father during his campaign for mayor. See it below:

The mayor also cited his son during a news conference this week, reacting to the news that a New York City police officer would not be indicted in the death of Eric Garner. The mayor, referring to Dante, said "A good young man, a law-abiding young man, who would never think to do anything wrong, and yet, because of a history that still hangs over us, the dangers he may face - we've had to literally train him, as families have all over this city for decades, in how to take special care in any encounter he has with the police officers who are there to protect him."

4] BEFORE HE WAS MAYOR:

Prior be his election as New York's mayor, De Blasio served as New York City's public advocate. Before that, he served on the New York City Council for nearly a decade. In 2000, the mayor managed the Senate campaign of former Secretary of State Hillary Clinton.
