WHO CARES??? Her `fame` is she is the grand-daughter of a very disturbed man. BIG DEAL!
She was born Margaux Louise Byra Hemmingway in Portland, OR. Her parents were separated when she was conceived. They had just consumed an expensive bottle of Margot wine together, hence her name. Her middle names were her mother`s. Margaux had another fling with the ubiquitous Warren Beatty and married 1977 Errol Wetson and 1979 Bernard Foucher. She OD`ed on drugs, 1996 Santa Monica, CA. Her dad, Jack (son of the famous Ernest), was a WWII hero (OSS) and an often published fly-fishing expert.
