Anna Lee originated matriarch Lila Quartermaine, with David Lewis being the first to play her husband Edward. Jane Elliot was cast as sharp-talking Tracy. The family owned business, ELQ Industries, named for the family's patriarch, Edward Louis Quartermaine, has been the center of several conflicts within the family.
The Quartermaines are notorious for their socialite status as well as their dysfunctional tendencies. Prone to comedic fights, they annually attempt to have a traditional Thanksgiving dinner only for it to be ruined and have to order pizza. At Christmas time, the family has been known for their annual Christmas reading at the Hospital's Pediatric Ward Christmas party, ever since the passing of former Chief of Staff Steve Hardy, until the party remained to be aired. In a 1992 interview, Stuart Damon described the family:
Once an integral part of major storyline arcs, the Quartermaines have seen a diminishing amount of screen time since 2006, and many characters of the family have died on-screen. Soap opera gossip website Daytime Confidential named the family to their list of Top 10 Travesties of 2007, stating: "No. 3: The Systematic Extermination of the Quartermaine family." The website speculated head writer at the time Robert Guza, Jr. was to blame, as they stated as No. 10 on their list of Top 10 Rivalries of 2007: "Guza vs. the Quartermaines and Their Fans: No battle on our list, save Viki vs. Dorian, has been fought for as long or as hard as Guza vs. the Quartermaine family and the fans who support them. The actors who portray(ed) Lila (until she died), Edward, and Alan were all fired at least once before fan outrage and campaigns brought them back in some form. The actors who portray(ed) Ned, Lois, Brook Lynn, AJ, Emily and Justus saw their characters written off or killed."
Characters currently on the show are noted in bold; family members through marriage are in italics. Only current spouses or those married at the time of their death appear here.
