Vidkun Abraham Lauritz Jonssøn Quisling () was born on 18 July 1887 in Fyresdal, in the Norwegian county of Telemark. He was the son of Church of Norway pastor and genealogist Jon Lauritz Qvisling (1844–1930) and his wife Anna Caroline Bang (1860–1941), the daughter of Jørgen Bang, ship-owner and at the time the richest man in the town of Grimstad in South Norway. The elder Quisling had lectured in Grimstad in the 1870s; one of his pupils was Bang, whom he married on 28 May 1886, following a long engagement. The newly-wed couple promptly moved to Fyresdal, where Vidkun and his younger siblings were born.
