The Palladian villa in Twickenham was built between 1724 and 1729 and was home to Henrietta Howard, Countess of Suffolk.
A mistress of King George II, she received a cash sum from the crown when she left court.
Over two-thirds of the settlement were shares in the South Sea Company which was heavily involved in the trans-Atlantic slave trade.
A Richmond Council Spokesperson said:
“We are aware that there are a number of buildings and road names in the borough that have links to this horrific moment in history. As Marble Hill House is not owned by the Council, I would hope that similarly to the Council, English Heritage will consider the findings from the London-wide Commission regarding how it will ensure that visitors to the attractive are aware of its link with this awful industry."

"English Heritage has commissioned - and continues to pursue - research into the links between the Atlantic Slave Trade and its properties, including Marble Hill House, in an effort to help communicate this difficult history. English Heritage is committed to telling the full story of the sites in its care, including those elements that are painful today. You can read more here
