Cavendish Bentinck, Duke of Portland's Coat of Arms

This kind of design for a coat of arms in four sections is described as 'quartered'. The cross in the first and fourth quarters was the arms of the Bentinck family, a noble family originally from Holland. Hans Bentinck had came to England with William of Orange and had been made Earl of Portland in 1689. The three stags heads in the second and third quarters. In 1795 Henrietta Scott, then owner of Kilmarnock Estate, married William Cavendish-Bentinck, Marquis of Titchfield. He was the son of the 3rd Duke of Portland, a very influential English aristocrat, who was Prime Minister in 1783 and 1807. An agreement was made that the Kilmarnock Estate could only be inherited by a descendant of Henrietta's. In 1809 the 3rd Duke passed away and Henrietta's husband became the 4th Duke of Portland and when he died in 1854, their son William became the 5th Duke and inherited the Estate.
