Can you describe Leafy Crawford from Their Eyes Were Watching God by Zora Neale Hurston?

In Their Eyes Were Watching God, Leafy Crawford is Janie's mother.  Leafy is mixed race, as Nanny was raped by the slave master in charge of her plantation.  Throughout Leafy's childhood, Nanny tried to protect her and give her a life that was better than the one Nanny had.  So Nanny runs away with Leafy from the plantation and finds a place to live in west Florida.  When Leafy becomes a teenager, Nanny has dreams that Leafy will become a school teacher; however, Leafy is raped by her own teacher and becomes pregnant with Janie.  The man is never charged because he runs away, and once Janie is born, Nanny is left in charge of raising the girl.  Leafy turns to alcohol to deal with her hardships and eventually runs off herself.  Janie knows little about her mother as a person.
