Carter's Chord singer Emily Robertson and Marc 'Butter' Fortney (formerly of Trailer Choir) had their first kid in October 2012. Tug Ryder Fortney came into the world at 7 lbs., 20 in. “I’m a pretty big dreamer and wide thinker, and it exceeded anything I could be ready for,” Fortney told Taste of Country. “It’s something sweeter than I ever thought it could be and feel like.” The boy isn't named after anyone in particular, the couple just liked the name Tug.
