The son of Longo Baggins and Camellia Sackville. He married Lobelia Bracegirdle and they had one son, Lotho.

Otho was a cousin of Bilbo Baggins and, he thought, his heir, so he and Lobelia eagerly waited for their inheritance, Bilbo's home at Bag End. But Bilbo made Frodo his heir, leaving the Sackville-Bagginses without any chance to get Bag End or any other inheritance.

Later Frodo however sold Bag End to Lobelia, but Otho never lived in the house he had desirded all his life because he had died six years earlier (SR 1412).
