Ensign Amarante Lebel was a 24th century Human woman who became a Starfleet officer during the Dominion War. She was the niece of Marie Picard, and honorary niece of Marie's brother-in-law, Captain Jean-Luc Picard.
In 2375, she had just graduated from Starfleet Academy, in a ceremony attended by her uncle, when the Breen attacked San Francisco. After the attack she helped her uncle and other new graduates operate Bunker SF-Zero-One, a back-up command center for Starfleet Headquarters. After the battle, she told Picard that she had requested duty on Earth to help it rebuild, and that she would stay in contact with him.
