Ard'rian McKenzie was a colonist on Tau Cygna V who helped Data persuade her people to leave and grew fond of him.
Ard'rian McKenzie lived in the colony on Tau Cygna V in The Ensigns of Command. When Data arrived to evacuate the colonists before the Sheliak returned, she was one of the few who listened to him and tried to help him win the others over.
Ard'rian was fascinated by Data and showed a romantic interest in him, which he did not quite know how to return. She stood by him against Gosheven's resistance and helped him reach the colonists, who in the end agreed to evacuate. Eileen Seeley played her.
