Agnes Maclehose, or Agnes Craig, known to her friends as Nancy and to Robert Burns followers as Clarinda, was a Scotswoman who had an unconsummated affair with Burns during 1787-88, on which he based the 1791 song "Ae Fond Kiss". The pseudonyms of her "Clarinda" to his "Sylvander" were adopted by the pair for confidential correspondence purposes. Maclehose, used here throughout, has been various styled, including "McLehose", "MacLehose" and "M'Lehose".
