Mrs. Floyd, Marion is the first wife of Heywood Floyd mentioned in Arthur C. Clarke’s novel, 2010: Odyssey Two. They have two daughters together, one daughter being born in 1994. Marion Floyd dies in an aircraft accident c. 2000 on flight 452 London-Washington, going down in the sea, off Newfoundland. Marion, although not mentioned by name, appears to be alive at the time when Heywood Floyd was on a birthday video-call with his five year old daughter in 1999, in Arthur C. Clarke’s 2001: A Space Odyssey.
Mrs. Floyd, Caroline is the second wife of Heywood Floyd in Arthur C. Clarke’s 2010: Odyssey Two and its film adaption. They get married c. 2002, after the death of his first wife. Caroline is a Marine Biologist and they have one son together, Christopher Floyd.
Heywood had met Caroline, one month after being appointed Chancellor of the University of Hawaii. They were watching the fire fountains of Kilauea with a crowd of tourists at the time they met. They have a twenty-year age difference between the two. Caroline is described as a good step-mother.
Being a family of two daughters, from the prior marriage, and having one son together, they occupy the Chancellor's residence. The home was built by a Marine Geologist for the acting Chancellor of the University of Hawaii. It’s built right on the edge of the Pacific Ocean, with an enclosure that allows for egress into the body of water. The dolphins routinely visit the dining room every evening. The family experienced a bad tsunami in 2005, which caused them to vacate the premises for a time.
Caroline is in her early thirties before Heywood leaves for the Jupiter Mission. She is worried when Heywood decides to go on the second mission to Jupiter, fearing that what happened to Discovery might happen to him. They ultimately divorce after Heywood Floyd’s long trip on the Leonov.
