Most studies of the case tell very few details about the slave woman who was the center of the story.
her name, where she came from and most importantly what happened to her and her baby after the events that led to the case.
You might want to check the Q&A section, where this question has been answered in more detail. The short answer, however, is that the slave woman's name was Margaret Morgan. She came to Pennsylvania with her husband from Maryland, where she lived on a small, apparently independent dwelling on a plantation. After the case, which determined that she should be returned to her owner in Maryland, she went back, at which point the records fall silent. It is not, in fact, even known that she went back to her owner or if she was sold to another owner.
