City Names

There are two lovely Portlands, in Maine and Oregon, but not many babies with their name. 

Portland

Brisk, preppy York is an underused classic with the potential to really shine in the 21st century. It's most familiar as a place name — York is a city in England — and surname. New York City and State were named after the Duke of York.
 
The most notable York in history was an enslaved man who was the only Black member of Lewis and Clark's expedition. York was a key member of the journey, skilled in hunting, medicine, and other survival skills. He was also invaluable in Native American diplomacy. At the end of the expedition, Clark denied York's freedom and instead sold him black into slavery.
 
Despite the sad ending to York's story, he is an American hero with a name worthy of consideration.

And as such it's inspired a plethora of place and company names, from the District of Columbia to Columbia University to Columbia Records, and songs like "Columbia, Gem of the Ocean." A character called Columbia appears in The Rocky Horror Picture Show.
