He married his wife, Kathy (Isabel Gillies) when they were both 17 years old, and at the beginning of the series, they have four school-aged children: Maureen (Erin Broderick), Kathleen (Holiday Segal in Season 1 and Alison Siko in Season 2 and 12), and twins Richard "Dickie" (Jeffrey Scaperrotta), and Elizabeth "Lizzie" (Patricia Cook). Richard (he stopped using his nickname upon entering adolescence) is named after Col. Richard Finley (James Brolin), Stabler's former commanding officer in the Marines, whom Stabler later arrests after discovering that he murdered a woman.
