Samantha Wildman was married to a Ktarian named Greskrendtregk and became pregnant with his child shortly before leaving Deep Space 9. By the time she discovered her pregnancy, Voyager was already in the Delta Quadrant. (VOY: "Elogium") She experienced many difficulties with this pregnancy, her first, including shooting pains in the lower back and the legs. (VOY: "Tattoo")
There were complications during the birth, and the child died. However, a subspace accident had duplicated Voyager and the duplicated child was returned to Samantha when her counterpart was killed. (VOY: "Deadlock") The child was later named Naomi.
After the Kazon captured Voyager and stranded the crew on a primitive planet called Hanon IV, Ensign Wildman's baby became ill and almost died. The chief of a primitive tribe native to the planet cured her with herbs and roots. (VOY: "Basics, Part II")
It was thanks to Ensign Wildman that Chakotay was able to remind Neelix, who had a crisis of faith, that his family was now the crew of Voyager, especially Wildman's daughter Naomi, who was very fond of him indeed and was actually Neelix's god-daughter. (VOY: "Mortal Coil")
In 2374, Ensign Wildman was part of a team headed by Seven of Nine, a group that prepared a harmonic resonance chamber to neutralize omega molecules; Wildman was assigned to bring the power relays online. (VOY: "The Omega Directive")
On an away mission, the Delta Flyer, crewed by Wildman, Tom Paris and Tuvok, was damaged by an ion storm, crashed, and was buried under rock on a deserted planetoid. Wildman was seriously hurt, bleeding internally. With their air running out, Wildman recorded a goodbye message to her daughter. Just before the air was depleted, the Flyer was dug out and transported to Voyager, saving the crew. After her injuries healed, Wildman visited a holoprogram, accompanied by Naomi, Neelix and Captain Janeway. (VOY: "Once Upon a Time")
