Kestra Troi (2329-2336) was the first child of Lwaxana Troi and Ian Andrew Troi. Being half Human, half Betazoid, it was unclear whether she would develop full telepathic abilities or only empathic ones. She died from drowning in Lake El-Nar on Betazed at the age of six, several months after the birth of her younger sister Deanna Troi. The truth about Kestra would not become known to Deanna until 2370, when a telepathic encounter with the Cairn unlocked the supressed memories within Lwaxana's mind. (TNG episode: "Dark Page")
