Krelik was a Klingon woman that lived in the 23rd century. She had a daughter, L'Naan. Her granddaughter was Miral, and her great-granddaughter's name was B'Elanna Torres.
In 2377, when a group of Klingon religious radicals came aboard USS Voyager, B'Elanna prayed for her grandmother and her great-grandmother. (VOY: "Prophecy")
