"Princess Sophia of the United Kingdom (Sophia Matilda; 3 November 1777 – 27 May 1848) was the twelfth child and fifth daughter of King George III ...
and Charlotte of Mecklenburg-Strelitz. Sophia is perhaps best known for the rumours surrounding a supposed illegitimate child to whom she gave birth as a young woman.
In her youth, Sophia was closest to her father, who preferred his daughters over his sons; however, she and her sisters lived in fear of their mother. The princesses were well-educated but raised in a rigidly strict household. Though he disliked the idea of matrimony for his daughters, King George had intended to find them suitable husbands when they came of age. However, the King´s recurring bouts of madness, as well as the Queen´s desire to have her daughters live their lives as her companions, stopped would-be suitors from offering for most of the princesses. As a result, Sophia and all but one of her sisters grew up in their mother´s cloistered household, which they frequently referred to as a "Nunnery"." - (en.wikipedia.org 19.09.2020)
