Annie was the daughter of Elsa and the sister of Gretchen Janeway. Consequently, she was the aunt of Kathryn Janeway. In 2316, she was only a baby when her father, a Starfleet officer, was killed in an accident.
In 2329, Annie convinced Gretchen into attending the party that Elsa threw for their stepfather Kurt, reminding her how good he had always been to the two of them. (VOY short story: "Uninvited Admirals")
