New Orleans Privateers - The War of 1812 included the Battle of New Orleans, where privateers (basically legal pirates) helped fight for the US in their victory.
Vancouver Pacifics - Vancouver is on the Pacific Ocean and grew when the Canadian Pacific Railway was built to connect British Columbia to Eastern Canada in the 1880s.
Los Angeles Pilots - For the Los Angeles Airport and the importance of pilots to Hollywood TV shows.
Washington Eagles - For the national bird of the United States that it also featured on many federal government seals and such. Color scheme could be red, white, and blue, or blue and bronze like federal seals.
Atlanta Capitals - Atlanta is the capital of Georgia and referred to as the "Capital of the American South" according to Wikipedia, so this could work (though my vote is for Firebirds...). Capitals could also refer to the importance Atlanta has played in the Civil Rights Movement as well.
Charlotte Maroons - The Queen City should be named appropriately, but names such as the Royals and Monarchs were already suggested. Why not go for a similarly classic Maroons name, which evokes the regal color of royalty in its name.
