Finding MERS securitization

Hi - has anyone found a way to find the actual security that their MERS mortgage was pooled into? I have tried several sites, EDGAR using the date of the closing and the name of lender, 8k and various combinations to no avail.   I do get hits that appear to be source code for fund info publications.    I have a loan number, a MOrtgage ID number and company actually shows another company name on website.   NE MOVES MORTGAGE, LLC is really PHH.    any ideas???     Xoxoxoxo Zha
