The family name derives from "Quislinus," a Latinised name invented by Quisling's ancestor Lauritz Ibsen Quislin (1634–1703), based on the village of Kvislemark near Slagelse, Denmark, whence he had emigrated. Having two brothers and a sister, the young Quisling was "shy and quiet but also loyal and helpful, always friendly, occasionally breaking into a warm smile." Private letters later found by historians also indicate a warm and affectionate relationship between the family members. From 1893 to 1900, his father was a chaplain for the Strømsø borough in Drammen. Here, Vidkun went to school for the first time. He was bullied by other students at the school for his Telemark dialect, but proved a successful student. In 1900, the family moved to Skien when his father was appointed provost of the city.
