Nancy Kress was married to Charles Sheffield.

Nancy Kress was born and raised in upstate New York, where she spent most of her childhood either reading or playing in the woods. She earned a bachelor's and master's degree in education, as well as an M.A. in English. While she was pregnant with the second of her two sons, she started writing fiction. She had never planned on becoming a writer, but staying at home full-time with infants left her time to experiment.
