Chief Edgar Willoughby was the sector quartermaster for Bajor sector in 2375. The name of his wife was Cynthia, and together they had two children: an eight-year-old daughter named Melissa, and a five-year-old son, Edgar Jr. He also went by the moniker of "Eddie". When Miles O'Brien needed a new graviton stabilizer for the USS Defiant in 2375, he gave permission for Nog to place discrete inquiries regarding the availability of such a device. Nog gave Willoughby a bottle of Gamzian wine as a gift, and learned that it would take a week to acquire the replacement, which was too long.
