"Queen Louisa Ulrika had a lady-in-waiting by the name Ulla Liewen, engaged to count Per Brahe, son of the unhappy count Erik. In 1769 she fell sick and was delivered of "The Petite", who was the daughter of Adolf Fredrik. The queen was informed of the secret, but out of friendship for her maid of honor, who had a good name for virtue and good customs - perhaps also in reference to the utter jealousy, which Her Majesty had displayed in the matter of the charming actress and dancer m:lle Dulondel, with whom the King had a son called Fredriksson, a jealousy which caused the exile of m:lle Dulondel from the realm - the queen promised her husband to care for the child under the vow of secrecy. Those, who have seen countess Stenbock in her younger years, as well as the portrait of Ulla Liewen, can not doubt the matter. Beside, she looks like Adolf Fredrik, and this explains, why people have found such as resemblance between her and princess Sofia Albertina".〔Cecilia af Klercker (1927).
