Frodo Baggins:

Born in the year 2968, Frodo Baggins was adopted by Bilbo Baggins as his heir, in the year 2980. Frodo's birthday was the same as Bilbo, September 22. In 3001, after Bilbo disappeared, Frodo took ownership of Bag End, and of the Ring, though at that time it was not know exactly what the Ring was, though Gandalf had some suspicions. In the year 3018, Gandalf finally discovered that the ring was the One Ring, and on September 23 of that year, Frodo left the Shire secretly with Sam, Merry and Pippin. After an adventure in the Old Forest, they met Tom Bombadil who helped them later escape the Barrow-wights. There they each received an old knife from the mound so that the spell on the mound would be broken. They met Strider in Bree, and he led them to Weathertop, where they were all ambushed by the Nazgûl. There Frodo was wounded by a Morgul-knife. Seventeen days later they made it to Rivendell, after another near escape from the Black Riders at the ford of Bruinien. At the Fords of Bruinien Two months later, with the addition of Gandalf, Boromir, Legolas and Gimli to the Company, they left to destroy the Ring in the Cracks of Doom in Mordor. This adventure is retold in the Lord of the Rings, as the selections from the Red Book of Westmarch dealing with this are now known.

Frodo left the Company at the Falls of Rauros, with just Sam and after several more adventures, including being captured by the orcs of Cirith Ungol, eventually made it to Mount Doom. There he attempted to claim the Ring for his own. However Gollum bit off the Ring along with Frodo's finger, and overbalanced, falling into the Cracks of Doom, with the Ring. Frodo was healed of all this by Aragorn, soon to be crowned King of Gondor. After the Midsummer, Frodo, Sam, Merry, Pippin and Gandalf, made their way back to Rivendell with Elrond and the others of his house. From there the hobbits made there way to Bree and back to the Shire, where they found Saruman in residence. After clearing the Shire of the ruffians that Saruman had brought in (chiefly a job of Merry and Pippin), Frodo went back to normal life as much as possible. Two years later though, he sailed into the West with Bilbo and the Keepers of the Three Rings. It is not known what year he died in, save that it was some time in the Fourth Age.
