Rostgaard von der Maase edit

Major Frederik Masius von der Maase (1696-1728), a son of Hector Gottfried Masius by his second wife, married Conradine Sophie Rostgaard (1704-1758), the daughter Frederik Rostgaard and granddaughter of Hans Rostgaard, thereby founding a branch of the von der Maase family that uses the name Rostgaard von der Maase.

Frederik Masius von der Maase (1696-1728) owned Tybjerggaard and Førslevgaard and acquired Stamhuset Kragerup with Krogerup Manor as well as most of the island of Anholt through his marriage.

Members of the family have owned a number of large estates and manor houses. These include Ravnstrup, Gunderslevholm, Førslev, Fuglebjerg, Lundbygård and Farumgård. Members of the family have also owned most of the island of Anholt since the 1820s.
