Hi Scott,
Do you have a marriage record for her? Or her parents' will/probate? While the FAG is clearly for the same person, there's no sources and not even a picture of her gravestone.
If you do the merge without sources you're basically saying "I, as the creator of this gedcom, intended this person to represent the same person as profile Blake-9984." Which isn't terrible because at least you're still around to tell what you intended, but it's not a position that someone else can verify.
