FW de Klerk was born in Johannesburg in 1936. He is the son of Johannes de Klerk (1903-1979) and Hendrina Cornelia de Klerk (1904-2001), who died just four months before the death of his former daughter Marike Willemse and his brother to Wimpie de Klerk (1928-2009). His family, whose name comes from the French surname "Le Clerc," "Le Clercq" or "de Clercq" is of Huguenot origin. He settled in the country in 1686, a few months after the Revocation of the Nantes edict, and participated in various events in the history of Afrikaner. Their ancestors participated in the Grand Trek on the train led by Piet Retief to get rid of the British rule. In 1838, three members of the Klerk family were also killed with Retief in King Kraal of Zulu, Dingane. Later, during the Second Boer War (1899-1902), the grandfather FW of Klerk was captured twice by the British before being a founding member of the National Party in 1914, alongside James Barry Hertzog. According to genealogist Keith Meintjies and confirmed by FW by Klerk, the latter is also in accordance with Krotoa (Eva), a female Khoi, who served as interpreter for the Dutch colonists during the founding of the Colony of the Head.
