Marianne was born in St. Louis, Missouri as an only child.  She said she was lonely because most of her friends had siblings to play with when they went home. When she was three and her father had completed his education, they moved to Illinois.  Marianne was thrilled when her parents adopted a three-year-old girl and her one-year-old brother.  They lived in a middle-class neighborhood next to a large grassy field near a church.  Many families lived in that neighborhood and there were lots of children to hang out with. Their father was a dentist, and their mother was quite ill with rheumatic heart disease.
