death and her executor, Bernard Lafferty, scattered her ashes into the Pacific Ocean as her last will specified. Rumors and accusations swirled after Duke's death, ranging from suicide to murder, and controversy was exacerbated by Duke's habit of regularly changing her last will and testament, but no court case was ever filed in the case. Net worth When Doris' father died, he left a fortune valued at $100 million, with the largest share going to Duke and her mother. Nanaline was a shrewd businesswoman, often compared to Hetty Green, and when she died in 1962, she left her daughter an estate then estimated to be worth $250 million.

In 1968, Duke created the Newport Restoration Foundation with the goal of preserving more than eighty colonial buildings in the town.
