>>46984 I'm thinking that the woman they were visiting was Lurline Roth the heir to the Matson container shipping fortune.

Lurline was born with her identical twin Berenice in San Francisco to Lurline Matson Roth and William P. Roth. Her father led the development of the famous line of Matson cruise ships and her maternal grandfather was Captain William Matson (1849-1917), founder of the Matson Navigation Company. Lurline and her sister Berenice and older brother William grew up in San Francisco and later at Why Worry Farm and Filoli in Woodside, California.
