Actually, the only source stating the connection to a sword is Ruth Noel's Languages of Middle-Earth, a book that is outdated and unauthorative. In Tolkiens universe, Bilbo is from Bilba, which is of unknown meaning, like the main entry says.
No matter how much of a fan you are of Lord of The Rings, it really would be unwise to name your child this - imagaine the tormet and bullying that would take place!

Like people have said before; this is not a baby name site but a name site. Some names on this site are clearly not meant to be given to kids but are just on the site to explain the meaning. I use Bilbo like dumbass or silly because it sounds so funny and I love the character Bilbo in LotR so it's not meant to be offensive.
