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.
Federal Hill, Baltimore
The neighborhood is named for the prominent hill that is easily viewed from the Inner Harbor area, to which the neighborhood forms the physical south boundary. The hillside is a lush green and serves as a community park. The neighborhood occupies the northwestern part of a peninsula that extends along two branches of the Patapsco River—the Northwest Branch (ending at the Inner Harbor) and the Middle Branch. This peninsula is generally referred to as the South Baltimore Peninsula, and includes the neighborhoods of Federal Hill, Locust Point, Riverside, South Baltimore, and Sharp-Leadenhall. While not physically a part of the peninsula, Otterbein is also included in the collection of neighborhoods which make up greater South Baltimore. Traditionally, Federal Hill was roughly triangular, bordered by Hanover Street to the west; Hughes Street, the harbor, and Key Highway to the north and east; and Cross Street to the south.
