For more than 50 years I have been a student of local history, though I haven't always conducted by studies in an orderly manner. In recent years I've felt that I was about as familiar with the general history of the Norwalk area as I needed to be, but was genuinely surprised to learn of a street name I'd never heard before.
What is now North Prospect from East Main north the one block to Monroe Street was known in the early 1830s as Cheapside. Actually, it was one of the few streets except for Main Street to have a name. Most of the side streets were simply known as "alleys" and ran one block from Main to what is now Monroe and Seminary. Monroe was then known as the North Street, since the town didn't extend north of it except along Whittlesey Avenue.
In November of 1832, David H. Fitch operated a store on the west corner of East Main and "Cheapside," and advertised in the Reflector (the paper you're reading right now) that that was his location. His was called the New York Store and he sold a general line of dry goods. He'd accept cash in payment, or most kinds of country produce.
The next month a tailor names Charles C. Monroe opened a shop on Cheapside Alley at No. 3. He was a "Scientific" tailor and must have been located in a building behind the Fitch store, which faced East Main. I couldn't find any other business advertisements for Cheapside businesses, but I did find that when David Fitch mortgaged his property in 1833 he described it as bordering on Cheapside Street, so the name must have been more or less official.
