Her personal motto - which can be seen on top of the gate to the court yard of Frederiksborg Castle - was: "Rege me Jehova spirito sanctu tuo" ("Guide me, Jehovah, with your holy spirit.")

The wedding took place in the castle of Haderslevhus in South Jutland the year after the coronation of Christian IV.

She had six children, among them Christian, the Prince-Elect, who died a year before his father, and Frederik III who introduced absolute monarchy in Denmark.

Their two daughters, Sophia and Elisabeth, and the elder son, Frederick, died at a very young age.

Despite her good relationship with the Lutheran bishop, she called upon a Calvinist vicar to give her the last sacrament on her death bed.
