Answer:
Nanny Crawford is specking these words to her granddaughter Janie mae Crawford.
The daughter referred to in the speech is Leafy Crawford, Janie's mother and Nanny's daughter.
Explanation:
The excerpt is from Zora Neale Hurston's novel "Their Eyes Were Watching God". This book revolves round the theme of the discriminatory lives of the blacks among the white folks.
The passage is from the second chapter of the book where Janie's grandmother had told her about her choice of husband for her granddaughter. She told her of her slavery birth, her upbringing n the plantations and how it was tough for a girl to be a slave. And that is why she had wanted her to marry Logan Killicks who may be a much older guy but have the means to provide security and social standing for Janie.
Nanny or Grandma Crawford is talking to Janie about the prospect of marrying Killicks.
"Mah daughter" in the speech refers to Nanny's daughter Leafy Crawford, Janie's mother.
