Brockhouse family
From Tolkien Gateway
Brockhouse was a populous family of the Bree-hobbits. Some members of the family lived in the Shire: Sapphira Brockhouse was the wife of Uffo Boffin, and Bilbo Baggins greeted the Brockhouses among other hobbit families in his famous farewell speech on 22 September, T.A. 3001.
Etymology
Brock is an old (up to the end of the 19th century) country word for "badger" and, in that Hobbit name, refers to its building complicated and well-ordered underground dwellings.
Tolkien noted that English placenames and surnames contain this old word, such as Brockbanks.[1]
