Christopher Billopp or Billop (ca.1638 - 1726) was an English officer of the Royal Navy in the seventeenth century who commanded various ships of the line including HMS Greenwich in the Battle of Bantry Bay Billopp was given a crown grant by James, Duke of York in 1676 for according to sources either 932 acres (3.77 km2) or 1,167 acres (4.72 km2), on Staten Island in the colony of New York, which became known as the Billop plantation. He built a stone manor house upon the land named "Bentley Manor", after the name of a small ship he had commanded, the Bentley. In 1687, he received a second crown grant. Although land ownership went through several hands, including those of William Henry Aspinwall, the neighborhood retained the Bentley Manor name into the early 20th century.
The house, inherited by his great grandson Colonel Christopher Billopp, a British Loyalist during the American Revolution, was the setting for a failed peace conference between Lord Howe and members of the Continental Congress. His house is now a United States National Historic Landmark known as the Conference House.
