There’s a long-established Rose Hill neighborhood in the Bronx; it’s the name of Fordham University’s campus.
But there was once a Rose Hill neighborhood in Manhattan too. The name came from Rose Hill, country estate purchased in 1747 by loyalist John Watts. It ran roughly from Park Avenue South to the East River between 23rd to 32nd Street.

Rose Hill lasted well into the 19th century: The New York Times archive contains articles referencing the Rose Hill Ladies Relief Union as well as the Rose Hill Methodist Episcopal Church on Third Avenue and 27th Street.
By the 20th century, the name seems to have been forgotten, the neighborhood absorbed by the Murray Hill-Gramercy-Flatiron region.
I couldn’t find a single drawing or painting depicting it, but there’s a building on 14th Street near Third Avenue that’s adopted the name.
Rose Hill might just be embarking on its second act. In the past decade, a crop of residents—and real estate agents—have begun reviving the name. There’s even a Rose Hill Neighborhood Association.
