What is the Giver's daughter's name?

From the text:

Jonas had been staring glumly at the floor. Now he looked up, startled. "I didn't know you had a daughter, Giver! You told me that you'd had a spouse. But I never knew about your daughter."
The Giver smiled, and nodded. For the first time in their long months together, Jonas saw him look truly happy.
"Her name was Rosemary," The Giver said.
