I don't remember if the author got around to giving her one. Mind you, this author has written quite a few different stories exploring various ways Seven and Chakotay could end up married. There's one where Seven was on a Borg cube that crashed on Chakotay's home planet. Seven was a teenager at the time, and it was Chakotay's father and the healers who figured out how to "de-Borgify" her. When the Cardassians destroyed the colony, both Chakotay and Seven joined the Maquis. It's an interesting twist to the story, and the action is all still pre-"Caretaker". Tom Paris has just joined the ship, and nobody knows Tuvok is a spy.
