Yes, Jill of the book, Jill's Gymkhana, a slightly unusual heroine I'm sure. She was a little girl who loved ponies but her mother was a widow like mine, so she lived a careful life, wore secondhand clothes and had to work hard to make her way in life. She found herself a pony, learnt to ride it by making friends with a disabled man who could teach her, saved her pocket money for the bits she needed and worked hard to make a success of owing a pony and doing it right. She was resourceful and focused on what she was keen on. Has always seemed a good role model in life!
