In Hope Was Here, what did Hope's mother name her when she was born?

In Hope Was Here, written by Joan Bauer, the main character's name given to her by her mother is Tulip. Her mother is barely present in her life, only popping up occasionally, and has abandoned her to the care of her Aunt Addie. Given her nearly nonexistent relationship with her mother and her dislike of the name "Tulip," she changes her name to Hope when she is twelve years old. Hope is supported in the name change by her aunt and ultimately decides on the name Hope because she believes hope to be the best thing that anyone could have. In fact, hope is Hope's guiding philosophy through the course of the book and she attempts to remain hopeful and optimistic in the face of difficulties and disappointments.
