Dear Mary:I was starting to type that I needed at least twp. information, when I saw in the index there was only one listing for Corwin.Here it is, verbatim.. I hope it helps you in some way.May I suggest you request from the National Archives the Military or Pension files on your Corwins?This might list parents names.-Jennifer
