My mother had a phone listing for ten years after she died. (Complicated reason but it happens.)
I have my Grandfathers phone nuumber and he died in 1954. People still think he needs his house resided.
Illness and death
In late 1994, Dunham was living and working in Indonesia. One night, during dinner at a friend’s house in Jakarta, she experienced stomach pain. A visit to a local physician misdiagnosed her symptoms as indigestion. Dunham returned to the United States in early 1995 and was examined at the Memorial Sloan-Kettering Cancer Center in New York City and diagnosed with uterine cancer. By this time, the cancer had spread to her ovaries. She moved back to Hawaii to live near her widowed mother and died on November 7, 1995, at the age of 52. Following a memorial service at the University of Hawaii, Obama and his sister spread their mother’s ashes in the Pacific Ocean at Lanai Lookout on the south side of Oahu. Obama scattered the ashes of his grandmother (Madelyn Dunham) in the same spot on December 23, 2008, weeks after his election to the presidency.
