Fru Marie Grubbe (1643–1718) was a member of the Danish nobility who drew a lot of attention by her many extramarital affairs. She has been the inspiration for books, plays and operas.

Ulrik Frederik Gyldenløve, Landgrave of Laurvig (20 July 1638 – 17 April 1704) was the illegitimate son of Frederick III of Denmark-Norway. A good relationship to his half brother, Christian V, secured him a position as one of the leading statesmen and largest landowners in Denmark-Norway. He was the leading general in Norway during the Scanian War, whose Norwegian leg is conventionally named the Gyldenløve War after him. He later served as Governor-general of Norway (Stattholdere i Norge) from 1664 to 1699. In Norway, he established the Countship of Laurvig and succeeded Peter Griffenfeld to the Countship of Tønsberg (until then Griffenfeld and later Jarlsberg). His extensive holdings in Denmark included Gyldenholm, Sorgenfri and Skjoldenæsholm.
