Dora was the only daughter of Fosco Baggins and Ruby Bolger. Dora was Frodo's aunt and the eldest surviving female relative of Bilbo and Frodo. A guest at Bilbo's Farewell Birthday Party, she received a large waste-paper basket from him, "in memory of a LONG correspondence." A prolific letter-writer, she filled her correspondence with good advice for many years. She never married.
She died five years after Bilbo's party and departure from the Shire at the age of one-hundred and four.
