1. Appleton’s Dictionary of Greater New York And Its Neighborhood (1905):

    Murray Hill

    This has been the most fashionable quarter of the city but there are indications that it will not retain the distinction many years longer, as people of wealth are gradually moving farther up town. The hill is bounded by 3rd Ave. on the east, 6th Ave. on the west, 32nd St. on the south and 45th St. on the north. The finest residences are on 5th, Madison and Park Avenues. The name is derived from the old Murray mansion, which stood on the hill years ago.
