The Marquess of Dufferin and Ava was a title in the British peerage created in 1871. The title is associated with the Dufferin family, particularly Frederick Hamilton-Temple-Blackwood, who was the first to hold it. He served as the Governor General of Canada and later as the Viceroy of India, playing significant roles in the British Empire during the 19th century. The Marquessate is named after Dufferin, a town in Northern Ireland, and Ava, a historical city in Burma. The title has been held by several descendants, contributing to British society and politics over the years.
