The wife of which king gave birth to a daughter who supposedly had an illegitimate child as a young girl?
Charlotte of Mecklenburg-Strelitz Charlotte of Mecklenburg-Strelitz (Sophia Charlotte; 19 May 1744 – 17 November 1818) was by marriage to King George III the Queen of Great Britain and Ireland from her wedding in 1761 until the union of the two kingdoms in 1801, after which she was Queen of the United Kingdom of Great Britain and Ireland until her death in 1818. She was also the Electress of Hanover in the Holy Roman Empire until the promotion of her husband to King of Hanover on 12 October 1814, after which she was also queen consort of Hanover.
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.
