The fierce Klingon, Lursa, sister of B'Etor (Gwynyth Walsh), in the ‘Star Trek: The Next Generation’ episodes "Redemption," "Redemption, Part II," and "Firstborn," the ‘Star Trek: Deep Space Nine’ entry “Past Prologue,” and the TNG feature “Star Trek Generations”. March also provided Lursa's voice for the video game “Star Trek: The Next Generation — Klingon Honor Guard”, and, frequently alongside Walsh, was a fan favorite at Trek conventions worldwide. March's husband, Alan Scarfe — himself a three-time Trek guest star — confirmed on Facebook that she passed away on August 11 at the age of 65.

Another 'Star Trek' celebrity has ascended to Sto-vo-kor.
Together with her Klingon sister B’Etor, she wreaked havoc in episodes of ‘Star Trek: The Next Generation’ (“Redemption” – part I and II, “Firstborn”) and ‘Star Trek: Deep Space Nine’ (“Past Prologue”). She also starred in the feature film “Star Trek: Generations”.
From Memory Alpha;
Lursa was a female Klingon officer of the 24th century Klingon Empire and member of the House of Duras. She was the elder of the two Duras sisters, herself and B'Etor, sister of Duras and daughter of Ja'rod. Through Duras, she had a nephew, Toral. She was the mastermind behind her family's fight to head the Klingon Empire.
Together with Be'tor, she was responsible for the beginning of the Klingon Civil War in 2367. With the assistance of the Romulans, Lursa and B'Etor plotted to install Toral, the illegitimate son of Duras, on the throne of the Klingon High Council. She attempted to persuade Jean-Luc Picard, who was the Arbiter of Succession, to rule in favor of Toral. When Picard supported Gowron, she and her sister took up arms against Gowron. Their attempt was defeated when the Federation blockaded delivery of supplies from the Romulans. When the Romulan involvement was exposed, Lursa's support evaporated. (TNG: "Redemption", "Redemption II")
In 2371, the sisters worked with El-Aurian scientist Tolian Soran and raided a Romulan outpost to acquire trilithium in exchange for Soran's trilithium weapon. Lursa died above Veridian III when her Bird-of-Prey was destroyed by the USS Enterprise-D. (“Star Trek Generations”)
