How are the words 'Suburb' and 'Superb' related to 'Superbas'?

Apparently, the "Superbas" name used for the Dodgers under the management of Ned Hanlon was a pluralized form of "Superba," a reference to an apparently somewhat well-known vaudeville production put on by the Hanlon brothers, an unrelated group of performers, acrobats, and inventors. I'm stumped as to any connection to the word "suburb" (beside a certain phonetic similarity).

I haven't been able to find any sources about the origin of the vaudeville event's name, but it looks to me like it's just the feminine form of Latin "superbus" in the sense of "excellent": "Superba" is apparently the name of a good character in the play.

This would make the 'Brooklyn Superbas' nickname ultimately related to the word "superb."

These two words aren't related; they have different roots from Greek and Latin. Superb uses the root super- while suburb uses the root sub-. Super- is for above while sub- is for below (See: List of Greek and Latin roots in English). The word suburb uses the sub and urb roots to make an under-city, or an outlying area of a city. The word superbas is still sub and not super because the sub root can be used as su/suf/sug/sup/sus and it creates confusion. In the case of it meaning suburb in latin, the "sup" part of the word refers to below, not above.

Another Latin word for suburb is suburbio.

Today in 1899, The Brooklyn Superbas Were Born by Alex Remington - February 7, 2013

Today in the 1898-1899 offseason, a remarkable thing happened: as the ownership groups in Baltimore and Brooklyn swapped part shares in each other’s clubs, the Orioles effectively merged with the Dodgers, with the class of the two ballclubs going to Brooklyn and the dregs staying in Baltimore — with the exception of star Baltimore third baseman John McGraw, who refused to leave. (Imagine if Jeffrey Loria traded a stake in the Marlins to Rogers Communications to obtain a stake in the Blue Jays, and you begin to get the idea.) The super-team in Brooklyn, formerly called the Trolley Dodgers, became known as the “Superbas.”

And this from http://www.boweryboyshistory.com/2011/08/brooklyn-baseball-superbas-and-worst.html:

A couple weeks ago I wrote about the daredevil vaudevillian acrobats the Hanlon Brothers, known for extraordinary feats of human agility mixed into theatrical extravaganzas. They made their debut at Niblo’s Garden in 1858, and fifty years later, their sons were still carrying on the tradition of thrilling audiences with their mix of fantasy, theater and gymnastics.

In the 1890s, the Hanlon sons focused their energies on two popular traveling variety shows, elaborate productions akin to a stadium rock show, often employing revolving stages, costumed casts, and sophisticated harnesses and props. The first, Fantasma!, would later be the subject of Thomas Edison’s early films. Their second, Superba!, would accidentally inspire the world of baseball.

In 1899, scrappy baseball superstar Ned Hanlon — who made his career in the 1880s in Cleveland and Pittsburgh — moved to Brooklyn to manage the then-named Brooklyn Bridegrooms. Ned Hanlon was not related to the flamboyant Hanlon brothers in any way. However, simply by confusion or a cheeky name-play by journalists, the team was soon called the Brooklyn Superbas, borrowing the title of the popular theatrical show. (You pronounce it the Su-PER-bas.) The name stuck until the early 1910s, when the borough’s primary form of transportation inspired another nickname — the Trolley Dodgers, soon shortened to just the Brooklyn Dodgers.

So I'm not seeing any connection to the suburbs here.
