In "The Lord of the Rings" which of these characters was one of Bilbo Baggins grandfathers?

Blinky, Those of us who know of Middlearth want to live there. My brother urged me to read The Hobbit and The Lord of the Ring trilogy. Once I started, I didn't want to be bothered by life's trivialities...like eating, sleeping, working or talking to people. It's like that. :)

If you haven't read the books (or gone the easier way and watched the movies), do yourself a favour. The most amazing story ever!

I love the lord of the rings
