Louis VIII
She was the daughter of Carl Ludwig Martini (d. 1698), an officer, and Susanna Catharina Meser. In 1744 her father, seeking a promotion, is alleged to have sent Helena to submit his petition to Louis VIII at "Jagdschloss" Kranichstein. When Louis VIII met her, he kept her as his mistress and did not let her return. Martini, who became known as "mamsell Lene", enjoyed the unlimited confidence of Louis VIII, was given a house in Darmstadt and accompanied him on his travels. She supported him in his political conflicts with the branches of the Hesse family, and brought the children of her sister to be raised in her care. She reportedly had a good relationship with the family of Louis VIII. Upon his death in 1768, she left the court with a fortune, which she later left to the children of her sister.
