Crosby was married to Geoffrey Edwards from 1983 to 1990 and appeared in a few of his father's films, including Skin Deep, Trail of the Pink Panther, and Curse of the Pink Panther.
Crosby is now married to Ken Sylk and has one son, August William Sylk.
Ultimately, Crosby decided to leave the show. Her character was unceremoniously killed by the alien creature Armus during the episode "Skin of Evil". She had starred in 22 episodes of the program at the point of departure.
In later years, Crosby had second thoughts about leaving the show, and approached the TNG production team with the idea of reprising her role of Tasha Yar. This came to be in season three's "Yesterday's Enterprise" in which an alternate timeline is created after the USS Enterprise-C, the predecessor to TNG's USS Enterprise-D, comes forward 22 years in time. Yar joined the Enterprise-C before it returned to its own time. During the documentary Trekkies, Crosby commented that her Tasha Yar character had to die in order to get "the best episodes".
Crosby would also guest star in several other TNG episodes, "Redemption" as Romulan Commander Sela, the half-human, half-Romulan daughter of Tasha Yar, who had been impregnated after being taken prisoner in the past after joining the crew of the Enterprise-C in "Yesterday's Enterprise". Crosby later reprised the role in the Star Trek: Armada video game.
Tasha Yar was also featured in the feature length final episode of the series entitled "All Good Things..." in which Captain Picard is moving back and forth through time. In the past Tasha is taking him by shuttle to the Enterprise for the first time and features throughout the episode.
Crosby produced and narrated the 1997 documentary Trekkies, followed by the 2003 sequel, Trekkies 2. Both films star Crosby, who conducts interviews with devotees of Star Trek, more commonly known as "Trekkies".
She will appear in an upcoming two-part episode of the Internet fan-based series Star Trek: New Voyages called "Blood and Fire", playing Dr. Jenna Yar, Tasha Yar's grandmother.
