If my wife dies before her father dies (who is leaving his inheritance to her) and her brother in the Will, who is the beneficiary then?

Depending on how the will is written, her children would inherit her share, unless the survivor of the beneficiarys is to receive, as providsed by the will. Or the provision could be to her issue(children) in the event of her death. Seek legal probate counsel to advise you and examine the will provisions.

Hello.  In Minnesota, as a general rule, the answer depends upon the wording of the will.  Sometimes, by operation of law, a person is entitled to a share due to one's legal relationship to the person who died.  To properly answer the question I would need to confer privately with you about the unique details to your situation.  I recommend one make several phone calls in choosing an attorney because it is so important that you feel a sense of great trust in the relationship.  Oftentimes a person in a situation you describe will have multiple legal concerns which we will discuss and address within the safety and privacy of the attorney-client relationship.
