Star Trek: Voyager - Season 5 Episode 23 -

The crew of Voyager swap stories of family histories. Janeway is most proud of her ancestor Shannon O'Donnell, who has been celebrated by the Janeway clan for generations as an astronaut and pivotal member of The Millenium Gate and several Mars projects that followed. When research and history-buff Tom Paris prove the stories wrong, that O'Donnell wasn't the hero Janeway made her out to be, the crew points out that her inspiration made Janeway join Starfleet and that is an accomplishment in itself.
