14th Street is a major crosstown street in the New York City borough of Manhattan. Presently primarily a shopping street, in the earlier history of New York City 14th Street was an upscale location, but it lost its glamor and status as the city grew northward. Within 1/2 Mile, 10 Mins walk, the Demorest family had their house, 63 Irving Place.
Irving Place is a small historic district. Most of the houses in the district were built in the aftermath of the opening of Union Square in 1839, after which the area became one of the most sought-after residential districts in the city. The houses were primarily made in the Greek Revival and Italianate styles, while later apartment buildings in the district were in the Renaissance Revival style.
At the same distance, we have 10 Astor Place, a short, two-block street near the Public Theater (Astor Opera House). Demorest W. Jennings, was in partnership with Little Joseph J., a Printer.
