Wanted to clarify a few things.
Steven Harris Weinraub is her father, Nancy Cecile Hill is her mother, and Sarton Brodie Weinraub is her brother. Steven and Nancy were married in Staten Island in 1972. Coco was born January 14, 1971, so it's likely she was born out of wedlock in New York.
Nancy's brother died in 2008. Sarton and Corinne are listed as his nephew and niece.

You can see Nancy is associated with Steven and Corinne in this listing.

Sarton is a psychologist.
