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
Midway between First Street and Clinton the boundary turns southeast to follow the rear property line of the lots on first, again the boundary with the Clinton Avenue Historic District. This line becomes Ludlow Alley shortly before North Hawk Street. After a short southward jog to take in the two properties on that street north of Clinton, it returns to the alley and follows it back to Clinton at Ten Broeck.
