I have potentially good and potentially bad news: The good news is that I do not see how your mortgages could have been wiped out in a Chapter 7. Yes, it is possible that the people who filed bankruptcy may have discharged their liability to pay the mortgages, but mortgages do normally stay attached to the real estate as a lien. Mortgages can generally only be stripped (i.e. completely wiped out) by motion in Chapter 13's under the right circumstances, but not in Chapter 7.
The bad news is that a "Notice of Chapter 7 Case Closed Without Discharge" doesn't normally do anything for the creditors. This just requires the people who filed bankruptcy to pay a fee to reopen their case to file the post-bankruptcy credit counseling certification, and then they will get a discharge. Even if they don't, the automatic stay will remain in effect, making collection impossible.
So, while I do not think a Notice of Chapter 7 Case Closed Without Discharge will do any good for a creditor, it is extremely uncommon for a mortgage to be wiped out in a Chapter 7.
I strongly suggest you take the documents you received from the Bankruptcy Court, the foreclosure action, and your mortgages to an attorney in your area for review. It is possible that you may be able to get money during the foreclosure sale if you do not sit on your rights. Of course, for you to get money the home will have to be worth more than the people owed on the first mortgage, which is very uncommon nowadays, but it is possible.
Sorry i don't have better news =( but I hope this helps and a positive feedback is always appreciated if this was useful to you.
