Today, Amy Carter (she kept her name) lives a quiet life in Atlanta with her husband and seven-month-old son, Hugo James Wentzel. She declines to be interviewed. She is a board member at the Carter Center, the human rights and diplomacy center established by her father.

Hugo? That's an unusual name to give to an American kid. Bet she named him after her daddy's compadre, Hugo Chavez.
