I am going to answer your question.
If you filed a chapter 7 the liens such as second mortgages are remain against the property. Only your personal obligation to pay under the promissory note is discharged. If you wished to attempt a discharge of a 2nd mortgage you would have had to file a ch 13 and do an Adversarial Complaint to determine dischargability. They would only discharge if your 1st mortgage balance was equal to or greater than the value of the property. From your figures it does not sound like it was.
I hope this was helpful. Please let me know if you would still like additional service, but frankly a review of the documents will not likely change my response.
