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.
Harbor Heights
Originally known as the Knolls, Harbor Heights was first developed by Harry Rich Mooney in the 1920s.
Mr. Mooney promoted the Knolls as a wholesome and convenient alternative to living in New York City and advertised the area in a nominal publication called Mooney's Megaphone in the New York Herald Tribune. Once Knollwood Avenue was established, other developers built homes east (across Mamaroneck Avenue) to the Mamaroneck River and the name Harbor Heights is inclusive of this area.
