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.
Judith of Bavaria (died 843) Queen Judith (797– 19 April 843), also known as Judith of Bavaria, was the daughter of Count Welf of Bavaria and Saxon noblewoman, Hedwig. She was the second wife of Louis the Pious, King of the Franks and Emperor of the Romans, which brought her the titles of queen and empress. Marriage to Louis marked the beginning of her rise as an influential figure in the Carolingian court. She had two children with Louis, a daughter Gisela and a son, Charles the Bald. The birth of her son led to a major dispute over the imperial succession, and tensions between her and Charles' half-brothers from Louis' first marriage. She would eventually fall from grace when Charles' wife, the new empress Ermentrude of Orléans, rose to power. She was buried in 846 in Tours.
