Bilbo Gardner was a Hobbit of the Shire. He was the tenth child and fifth son of Samwise and Rosie (Cotton) Gamgee.
History
He was born in FO 15, or 1436 by the Shire Reckoning, and named after Bilbo Baggins, his father's former master. He and Bilbo Baggins never would have met however, as Bilbo Baggins had already sailed away to the Undying Lands.
