Princess of the United Kingdom (1777-1848) who was the twelfth child and fifth daughter of King George III and Charlotte of Mecklenburg-Strelitz; she is perhaps best known for the rumors surrounding a supposed illegitimate child to which she gave birth as a young woman. Two ALSs, signed "Sophia" and "S," five total pages, both 4.5 x 7, no date. Penned in her difficult-to-decipher hand, both letters feature familial and political content. In overall fine condition. Accompanied by an unsigned engraving.
