Seven years into their relationship, Mia and Woody had Satchel "Ronan" O'Sullivan Farrow together. Ronan is the couple's only biological child together.

Ronan graduated from Bard College at the age of 15, and his impressive resume includes being a Rhodes Scholar, working as an adviser to then-Secretary of State Hillary Clinton, and investigating allegations against Harvey Weinstein for The New Yorker. 

The 33-year-old no longer has a relationship with his dad, though Mia herself suggested in 2013 that it was possible that Frank Sinatra was actually Ronan's biological father. In addition to continuing his reporting, Ronan appears regularly on Today, and he's worked on documentaries for HBO.

He's engaged to podcast host and former White House speechwriter Jon Lovett, whom he began dating in 2011.
