The Vos Clan referred to Quinlan Vos and his descendants. Quinlan Vos was a Jedi Master of the Old Republic, and at the time that Order 66 was executed, he went into hiding. When Korto Vos was born, he was sent to live with Khaleen on Naboo, where the Vos name became a curse after Imperials invaded their homestead, killing Khaleen. It should be noted that Xander Vos was the first of the New Jedi Knights of the family. As of c. 90 ABY, Ben Vos, Vikro Vos, Tyler Vos, and Lysa Vos were the last surviving members of the Vos clan.
