Wilhelmine’s husband was also named Friedrich and he also played flute and took lessons from Joseph Joachim Quantz. They were married in 1731, had a daughter in 1732 and officially became the Margrave and Margarine of Bayreuth in 1735. Wilhelmine’s father-in-law was similar to her father in that he was very frugal, pious and thought music and literature were a waste of time. Friedrich, however, was more like Wilhelmine and they set about making Bayreuth a cultural hub.

Princess Friederike Sophie Wilhelmine and Frederick II (later Frederick the Great) were the two oldest surviving children of Frederick Wilhelm I, King of Prussia and Sophia Dorothea of Hanover. While they were children, their grandfather, on their mother’s side, became King George I of England. It was their mother’s dream to have a them marry their cousins in a double wedding - Wilhelmine to the Prince of Wales and Frederick to the Princess Amelia of Great Britain. (Wilhelmine’s parents were also cousins.)
