Adopted daughter, no.
In a formal sense perhaps not, although I can easily see Saavik being legally Spock's adopted daughter if you buy into the Saavik back story of being a half Vulcan half Romulan from a Romulan planet and Spock found her and took her into his family. That's all non-canon conjecture of course.
My memory's a little shaky on this one, but didn't at least one of the novels have Saavik adopted by Sarek & Amanda? So instead of his daughter, Spock would have married his adoptive sister.
