Both of them passed away in their Brookline, Massachusetts, home after 66 years of marriage. Regarding his deceased father, Conan, 61, told The Boston Globe.

“I will be receiving calls from individuals who want to speak with me about my dad for the remainder of my life.

He’s my father, and I’ve never encountered anybody like him. I would ask myself, “Who the hell is this guy?” if I were to run into him in a hotel lobby. “He’s the most fascinating individual I’ve ever encountered.”
