Gathorne-Hardy is the name of a British aristocratic family.
The first part of the name is pronounced with a long a, i.e. "gay-thorn".
The founder of the family was Gathorne Gathorne-Hardy, 1st Earl of Cranbrook.
The "eccentric Gathorne-Hardys" as they are sometimes known,[citation needed] have produced many notable members of 19th and 20th century British society.
