Alexandra

From Memory Alpha, the free Star Trek reference

Alexandra was a Human child aboard the USS Enterprise-D in the 24th century. Alexandra was one of several Enterprise children kidnapped by the Aldeans in 2364 in an effort to re-populate their planet.

Alexandra was taken from her quarters while her mother, Toya watched. The youngest of the kidnapped children, Alexandra had little trouble adapting to her new surroundings and became attached to Rashella. Even so it wasn't long before she became homesick for her mother. Along with the rest of the children Alexandra was eventually returned to the Enterprise where she presented Captain Picard with some flowers to thank him for securing their return. (TNG: "When The Bough Breaks")

Alexandra was played by twins Jessica Bova and Vanessa Bova
