Boston

Boston is a large city on Earth, located in the United States of America. Part of the state of Massachusetts, the city was founded in 1630. Boston later played a major role in the American Revolution, and following the war became one of the most populous cities of the New England region of the United States.

While visiting Earth in the late 19th century, Guinan claimed that she was a member of a prominent Boston family. (TNG episode Time's Arrow).

The Red Sox was a professional baseball team based out of Boston. Jake Sisko and Kasidy Yates once attended a holo-program of a game between the 1978 Red Sox and 1961 New York Yankees. Benjamin Sisko was unable to attend because he was on duty at the time, but correctly predicted a Yankees victory. (DS9 episode For the Cause).
