I think that there is 3 option in case of incomplete information.
Do not resurrect at all.
Resurrect one individual, filling gaps with random quantum noise.
Resurrect all possible individuals with all combinations of noise.
I suggest to choose variant 2. In this case everybody is happy. The subject is almost exactly resurrected in one of the universes. Each universe get a person which corresponds its conditions and do not get useless semi-copies of the subject.
