David is Niles' and Daphne's son. He was born in the two-part episode Goodnight, Seattle. During Daphne's pregnancy, it is implied he takes after his low-brow uncles (Daphne's brothers); for example, kicking away classical music. He was born in a veterinary clinic and is named after show creator David Angell; Angell and his wife Lynn both died aboard American Airlines Flight 11 during the September 11, 2001 attacks.
