It does not depict the more famous Countess of Chinchón who became the namesake of the cinchona genus of trees and shrubs responsible for early modern quinine production.

Maria Teresa of Bourbon y Vallabriga, Countess of Chinchón and Marquis de Boadilla del Monte (1780–1828) was the eldest daughter of the morganatic marriage of Infant Louis Antoni Bourbon and Maria Teresa de Vallabriga y Rozas, daughter of a cavalry officer.

Infant died when Maria Teresa was only 5 years old, she was then taken from her mother and brought up together with her younger sister in a monastery in Toledo.

Thanks to the Queen's protection, Godoy's career progressed rapidly from a colonel in the royal guard to the first minister who exercised effective power in the state.

The Countess regained numerous privileges lost as a result of her father's exile, such as the use of the name and coat of arms of the Bourbons.
