The first name Lorne is of Scottish origin, derived from the Gaelic 'Lochornan', which means "noisy sea". It was initially used as a surname but has since evolved into a given name. The name gained prominence in English-speaking countries during the 20th century and is often associated with the Canadian city of Lorne, named after an early governor-general of Canada, Lord Lorne.
The name Lorne saw peaks in popularity during the late 1940s to early 1960s, with a noticeable decline thereafter.
