The house was added to the National Register of Historic Places on March 24, 1978, for its significance in architecture, exploration/settlement, industry, and social history.

That period included a partnership with George La Monte to manufacture safety paper for use by banks, investment firms, and the federal government.

In 1909, a Chicago politician and lawyer named Dan McGinnity purchased the Kingsland Manor to use as a training site for pugilists.

Katherine Agnes McGinnity ran the Kingsland Manor as the Nutley Private Hospital until 1938, when she lost the property to taxes.

In 1941, while the Smiths were living there, the Kingsland Manor was documented by the Historic American Buildings Survey (HABS) program.

In 1971, the Schepps sold the Manor to a developer who approached the Nutley planning board with a proposal to subdivide the property and build four modern homes in its place.

In recognition of the fact that the HABS program had found the Manor historically significant, the planning board turned down the proposal and chose to purchase the property with New Jersey Green Acres Funds.

Exhibits from the Roaring Twenties include items that belonged to Bus McGinnity and his wife, Lulu, and a newly restored speakeasy.
