Cities in New York

I'm going to New York City this week and it made me think about cities in general and the people who live in them. New York is an "er" city where the people who live there are New Yorkers. Other "er" cities would be Detroit, Berlin, London and Cleveland.

Other cities are "ian" or "an" cities. Paris is an example where the people are called Parisians. Others that come to mind are Philadelphia, Chicago, Rome, Atlanta and scores of others.

What do you call the people from Coxsackie?
