She's happy they share the same blond hair and blue eyes, but she struggles to revisit 9/11.

Rodney Wotton, 9
On Rodney's bed there is a stuffed dog that his father, 36-year-old IT manager Rodney Wotton, picked out for him before he was born. He loves the similarities he and his dad share (including a love of spaghetti), but feels the attack on Tower 2 that left him fatherless is unfair. "I think of my dad when I'm really mad," Rodney tells PEOPLE. "Probably because he would take my side."

Grace Danahy, 9
Grace used to keep her ultrasound picture in her room because it was the only photo her father, Patrick Danahy, had seen of her before his death at 35 in the collapse of Tower 2. Though she is close to stepdad Andy Sammel (whom she and sisters Katie and Allison call "dad"), she asks her mom Mary to tell stories about "Daddy Patrick," and sleeps every night with one of his bike jerseys.
