I believe she will found to be intestate as well.
I don’t think we can *count* on that. I’m seeing legal opinions that say that those couple of controversial clauses about “child” and “children” can be argued and the whole thing can still stand on intent.
It’s not like if a witness lies about one thing, you can throw out all his or her testimony. Each part of the will can be tested or not, but the whole may stand.
