Shenara

From Memory Alpha, the free Star Trek reference.

Shenara was the daughter of the Klingon emperor Reclaw of the Second Dynasty, who was put to death after her father was overthrown. At the beginning of the Third Dynasty, a concubine named Karana was given Shenara's name and title.

Sirella claimed that her 23rd maternal grandmother was Shenara, though she was actually Karana. (DS9: "You Are Cordially Invited")

According to the episode script, the new "Shenara" later married Keltar, son of Torva, in the Year of Kahless 152.
