Samwise Gamgee: Born April 6th, 2983 in the Shire to Hamfast Gamgee and Bell Goodchild. He was the fifth of six children (Hamson, Halfred, Daisy, May and Marigold were his siblings).
He and his family lived at Number 3 Bagshot Row, Hobbiton.
By the time of Bilbo's eleventy-first birthday party, Sam had taken over the tending of the garden at Bag End from his father. Bilbo had been teaching him to read and write, and few stories of the Elves. He had always wanted to meet elves, as he had never been out of the Shire until the quest.
He was chosen to accompany Frodo by Gandalf when he found him eavesdropping outside one of the windows of Bag End. He was also in league with Merry and Pippin, and told them about Gandalf's plan for Frodo to leave the Shire.
In Rivendell, he stayed by Frodo's bedside as he recovered from his wound. He also snuck into the Council of Elrond and insisted on going with him.
Throughout the whole quest, he stayed with Frodo. He cooked them meals when he could while they marched through Mordor. He carried Frodo when he got too tired.
When he thought Frodo was dead in the pass of Cirith Ungol he took Sting, the Phial of Galadriel, and the One Ring from his seeminglessly lifeless form, and so was a Ringbearer, if only for a short amount of time. He rescued Frodo, and helped him on the final steps up to Mount Doom.
When the War of the Ring was over, as was the Scouring of the Shire, he married Rosie Cotton. He was elected Mayor of the Shire seven consecutive times starting in 3027 of the Third Age, and was a very well-respected gentle Hobbit.
