How can one find out where a mortgage lien on his home originated? - first lien mortgage

I was born on the search for a lien on the mortgage of a person. Only to learn that there is a lien on your mortgage, but can not remember the location of your house as collateral, or something. I did an initial search on the net, but I do not know where to start.
