Jenza

Jenza was a Serennian female, the daughter of Count Gora and Countess Anya, and the younger sister of Dooku and Ramil. Gora abandoned the Force-sensitive Dooku to be found by the Jedi Order, becoming a Jedi initiate. Among other initiates, Dooku returned to Serenno during a festival, encountering Jenza and discovering who she was. After returning to the Jedi Temple on Coruscant, Jenza and Dooku secretly continued to communicate. She thought highly of her Jedi brother and longed for Ramil to act more like him, much to Ramil's annoyance. In time, Ramil plotted to murder both Jenza and Dooku with his security droid plot in 42 BBY, yet he would be defeated and killed by Dooku, who left the Jedi and took on the title of count to rebuild Serenno himself.

Around 23 BBY, after Lady Jenza had seen Dooku increasingly give into darkness at the urging of a hooded figure, she was kidnapped by Galactic Republic-backed agents. Dooku tasked his apprentice Asajj Ventress to track her down. Although Ventress did not know it at the time, Dooku's intention was for Ventress to continue in her role of his personal assassin by killing his sister, as he feared Jenza planned to reveal his secrets to the Republic. Jenza pleaded with Dooku to contact the Jedi and not continue down the dark path he was on, but Dooku was not persuaded and had Ventress execute her, thus severing his ties with the past.
