Hi PC,
I can perhaps try some suggestions from memory :) for your daughter.
I remember reading age appropriate biographies of:
Florence Nightengale
Amelia Earhardt (the pilot)
Diary of Anne Frank (a tough read so you need to judge if this is an appropriate age)
Clara Barton
I bet there are biographies out there of also
Harriet Tubman
Susan B Anthony
...
Best of Luck
Jilly
