When a beneficiary dies before the testator then
(a) if the beneficiary was a child of the testator and had children of their own, anything which was destined for the beneficiary passes, in equal shares, to their children ;
(b) if the beneficiary was a child of the testator but had no children OR if the beneficiary was not a child of the testator, then where there is a 'residuary beneficiary' (i.e. the will says something like "Everything else I leave to Fred Bloggs") then what should have gone to the deceased beneficiary passes to the residuary beneficiary ;
(c) where the circumstances of (b) apply, but there is no 'residuary beneficiary' (or if the residuary beneficiary also pre-deceased the testator) then a 'partial intestacy' is created, meaning that whatever should have passed to the deceased beneficiary has to be allocated according to the rules on intestacy.
So what the wife left to her daughter, in your question, would pass to that daughter's children if she had any. I assume from the wording of your question though that she didn't, so whatever should have gone to the daughter now has to be dealt with under the intestacy rules (UNLESS the the wife's will named a residuary beneficiary, in which case it goes to them instead)
Similarly, what the wife intended to go to her husband must now also be dealt with under the intestacy rules (again UNLESS there was a residuary beneficiary in the wife's will).
