This is actually a fascinating subject.

The suffixes on many names in the US are European based naming standards abbreviated and shortened. The use of them has something to say about where our country was when these cities were founded.

-ton & -town is British based. -ton is a shorterned -town. Hampton would be the Town of Hamp and it likely had some relationship with another city or person named Hamp or Hamp is an abbreviation of a longer name. -boro is another such English name. It was also common practice to put the type of place at the end in English city names. The name of a river, mountain, creek, woods, so -mont, -port, -wood, -land, -hills was a direct alteration to the naming standards English used to describe what their town was through the name. -mouth would also be the mouth of a river.

-burg is German for castle. Many Germanic cities had small castles that were the banks of their day to protect the cities valueables, so -burg stuck as an informal name for a small city. The areas where these are mapped goes into the Midwest where Germans heavily settled the area.

-ville is very important in American history. It is pervasive throughout the east coast and eastern midwest. Any area with towns settled in the few decades after the success of the American Revolutionary war gave a great deal of praise to France for their assistance. It comes from the name for a French town Ville. So Lawrenceville is Ville Du Lawrence, the Town of Lawrence. It was likely founded by someone with the last name Lawrence, but the Ville came from Americans trying to shed names from Britain, like -ton, and thanking the French for their assistnace. Sadly, because of the linguistic differences between French and English many often take -ville to sound antiquated, substandard, backwards, etc... But it actually has its roots from a very important piece of American history and was to thank the French for their help.
