Sheridan Hollow, Albany, New York
On a map made by De Witt in 1790 the name of Arbor Hill makes its first appearance on a map of Albany. In this map Arbor Hill is located in Sheridan Hollow between Orange Street and Clinton Avenue (south and north) and from Chapel Street halfway to Hawk Street (east to west); later Arbor Hill would be the name given to the Ten Broeck Mansion and surrounding neighborhood on the other side of Clinton Avenue, the former village of Colonie. On this same map a "Negro burial ground" is shown along the southern rim of the Hollow, this burial ground does not show up on any subsequent maps and it may never have been plotted and used.
Forest Hill, Newark, New Jersey
Forest Hill is located on a ridge between the Passaic River and the valley of the Branch Brook. It was first developed by Elias Heller, who owned a file factory in North Newark, on the Belleville border. Heller Parkway is named in his honor. From the 1870s to the 1920s, generations of wealthy Newarkers built hundreds of stately homes in the area in various styles, including Beaux-Arts, Victorian, Colonial Revival, Gothic Revival, and Spanish Revival. Along with their mansions, the wealthy of Forest Hill also developed scores of social and literary clubs. Other than the homes, landmarks include the old Tiffany factory. The Branch Brook branch of the Newark Public Library serves the neighborhood.
