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
Ten Broeck named the mansion Prospect due to the commanding view it offered of the Hudson and its river traffic (some other accounts suggest he called it Arbor Hill from the beginning). He lived there until his death in 1810; Elizabeth survived him by three years. By that point a few other houses had likely been built nearby, but not enough to constitute a neighborhood, even after Colonie was annexed by the city in 1815. The mansion was sold to new owners who, over the next three decades, refurbished and expanded it with elements of the similar Greek Revival architectural style.
