Poppy Chubb-Baggins
From Tolkien Gateway
Poppy Chubb-Baggins was the daughter, and only child, of Falco Chubb-Baggins. She married Filibert Bolger, and thereby brought the family name of Chubb-Baggins (derived from her grandparents Chica Chubb and Bingo Baggins) to an end. Her grandfather Bingo was an uncle of Bilbo Baggins, making Poppy Bilbo's first cousin, once removed.
