"Therese Concordia Maron (née Mengs) (1725 – October 10, 1806), was a German (Saxon) painter, for most of her life active in Rome. She was the ...
elder sister of more known painter Anton Raphael Mengs.
Therese was born in northern Bohemian town of Ústí nad Labem (German: Aussig) into the Lutheran family of Danish painter Ismael Mengs, a hofmaler (court painter) at the court of Saxon-Polish electors and kings. Her birth in Bohemia was mere coincidence, because her father maintained an extramarital relationship with his housekeeper Charlotte Bormann and in an effort to conceal the birth of an illegitimate child, he decided to take the mistress under the pretext of "vacations" to the nearest bigger town abroad, namely to Ústí nad Labem (90 km upstream of the Elbe River), where she gave birth to daughter Theresa Concordia. After a few weeks, Mengs took his daughter and her mother back to Dresden, the Saxon capital, where they lived. (Three years later he made the same trick even with the birth of his son, Anton Raphael)." - (en.wikipedia.org 26.10.2020)
