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.
Arbor Hill Historic District–Ten Broeck Triangle
While the former burying ground site was made into a park instead of being built on, construction on other parcels increased. The year the burying ground was moved, 41 Ten Broeck Street, the earliest dated house on that street after the mansion, was erected. The brick rowhouses at 15–23 and 35–39 Ten Broeck followed as well. In 1848, the neighborhood regained some of its original prestige when Thomas Worth Olcott, a prominent banker, bought the Ten Broeck Mansion and formally renamed it Arbor Hill. He and his family expanded it over the next several years. The King Building, an elaborate Greek Revival duplex, was built over four years in the 1850s at 27–29 North Swan in front of the archway that provided access to the mansion's grounds on the rear.
