Her brother, husband and extended relations were eventually caught up in the religious wars of the century. Sibylle, however, had more troubles at home. Just before her 25th birthday, she married Duke Francis I of Saxe-Lauenburg. Despite having nine children together, theirs was a rocky relationship. They separated and reunited more than once. Unlike in other royal marriages, however, it was the wife who was accused of "vindictive and unloving acts."
The relationships with and among their children was no less complicated. The marriage lasted four decades until his death. Having plunged his territories deeply in to debt and pawned off some of his demesnes, Francis abdicated in favor of their eldest son Maurice, who had promised to use the money from his Swedish marriage to restore the treasury. When he didn't do this, Francis deposed him and reasserted himself as Duke. Magnus gathered an army and returned but, with the help of his second son Francis II, Francis defeated him. He then named son #2 his heir, in violation of the laws of inheritance. After Dad's death in 1581, Francis II with help from little brother Maurice, warded off Magnus and imprisoned him for the rest of his life.
Meanwhile, Sibylle was not making things any easier for her sons. In fact, she so disapproved of Maurice's mistress, Gisela von Tschammer, that she brought charges of witchcraft against her.
Her daughters' lives were not so dramatic. They all married various German Dukes. Dorothea's husband built the pleasure gardens at Herzberg Castle for her, although she had no children. Ursula gave her husband five children. The youngest Sidonia Catherine, lost her first husband, by whom she had six children in 12 years, and remarried another Duke.
Sibylle died in 1592 at the age of 77.
