The wife of which king gave birth to a daughter who supposedly had an illegitimate child as a young girl?
Princess Sophia of the United Kingdom Princess Sophia of the United Kingdom (Sophia Matilda; 3 November 1777 – 27 May 1848) was the 12th child and 5th daughter of King George III and Charlotte of Mecklenburg-Strelitz. Sophia is perhaps best known for the rumours surrounding a supposed illegitimate child to which she gave birth as a young woman.
Adelaide of Hungary Adelaide of Hungary (  1040 – 27 January 1062) was the only daughter of King Andrew I of Hungary of the Árpád dynasty and Anastasia of Kiev. She was the second wife of Vratislav II of Bohemia, whom she married in 1058. She was a good dynastic match for Vratislav, as he profited from the alliance with her father. They had four children, including Bretislaus II of Bohemia and Judith of Bohemia. Vratislav became duke in 1061 after death of his brother, thus Adelaide was duchess for only a short time before her death early in 1062.
