benifits

I think it's unlikely you can determine this information, due to privacy rules.

SSA has this stated policy :

For information about potential benefits on someone else's record, you should call or visit your local office. If your former spouse is still living, privacy rules prohibit us from giving you his or her record, so we can't give you his Statement. But we can tell you what benefits you may be entitled to, after we have established your relationship to him.
