Vennerson, also known as Count, had a female offspring who was a first year student at Reena University on the world of Reena, circa 396 BBY. At approximately that point in time, Vennerson, while present at a celebration for that year's Queen's Bloom Festival on Reena, suggested to their associate, Galactic Republic Senator Lexxir Greylark, that he facilitate an introduction between his male offspring, Axel Greylark—who was also a student at Reena University—and Vennerson's daughter.
The short story "The Queen's Bloom," penned by Zoraida Córdova and featured in the 2023 young-adult collection The High Republic: Tales of Light and Life, which itself is part of the Star Wars: The High Republic multimedia initiative, included a reference to Vennerson's daughter.
