Have you ever been curious about where the name of your street (or any street) in Chicago originated?  This document will probably let you know.

I had no idea whom my street was named for until now:

Barry Ave., 3100N 314 to 7600W. Named after John Barry Commander of the Lexington during the Revolutionary War. He was born in Ireland and entered the U.S. service in 1776. He is considered the Father of the American Navy.

A more well known street as an example:

Belmont Ave., 3200N 400 to 9000W. First Civil War battle in which Grant commanded the Union Army at Belmont, MO.
