What does Jill do from The Girl Who Owned a City?

I have this school project to finish for Wednesday... and I have to find information on one of the characters of the book, "a girl who owned a city". So, I chose Jill and all I know is that she took care of orphans.. If you had anymore information about Jill, please let me know. I need at least 3 things. Thank you for your time and help.
