Lettice Hannah Earlwood is the youngest daughter of Mr. and Mrs Earlwood. Her elder sisters are Mary and Harriet, with Mary being the eldest.
She is known to be playful and cheerful, as expected for her age, with a fondness for dolls and dollhouses. Though in the game she could throw a tantrum when she did not receive the dollhouse that she wanted, she was scolded by Anna and was told that is not a behavior that is suitable for a lady and she calmed down eventually. Anna later made her a dollhouse herself.
Lettice also has a good friendship with the Protagonist since her older sister Mary is good friends with her, and she wishes the Protagonist well whenever she is about to marry.
