The Swamp

From Charles Addams, Wikipedia.

Addams married his third and final wife Marilyn Matthews Miller, best known as "Tee" (1926–2002), in a pet cemetery.  The Addamses moved to Sagaponack, New York in 1985, where they named their estate "The Swamp".

Addams died on September 29, 1988, at the age of 76, at St. Clare's Hospital and Health Center in New York City, having suffered a heart attack after parking his automobile. An ambulance took him from his apartment to the hospital, where he died in the emergency room.  As he had requested, a wake was held rather than a funeral; he had wished to be remembered as a "good cartoonist".  In accordance with Addams's wishes, he was cremated, and his ashes were interred in the pet cemetery of "The Swamp" estate.
