Lee married his wife, Amy Suntipah, sometime prior to 2354. On 1 April 2354, Amy gave birth to their only child, Corey.
Pressed for officers to man any available ship in light of the Borg attack in 2366, Aster and his wife were both summoned for duty aboard the USS Melbourne to defend the Federation at Wolf 359. The Melbourne was severely crippled at the Battle of Wolf 359 and it was assumed most of her officers were killed in the onslaught.

In 2367, during Corey's shared dream phase, he pulled Lee and Amy Aster, now both assimilated Borg drones, into his dream. With the help of Counselor Daniel Radke, Lee was able to make contact, breaking the hive mentality for a few moments, before succumbing to it again.

- Lee Aster's name comes from a post on the Hidden Frontier forums by the actor portraying Corey Aster, J.T. Tepnapa, when asked to "flesh out" his family.
