I HAVE READ SEVERAL BOOKS FROM ST. TAMMANY PARISH THAT IN SOME ENTRIES THEY SPELL GUZMAN, IN SOME IT'S GUSMAN, AND IN SOME IT'S GUSSMAN. WITH THE SAME FIRST NAMES, SO YOU MAY WANT TO TRY AND LOOK AT ALL SPELLINGS, TO FIND PEOPLE. MOST OF THEM WERE FROM ST. TAMMANY PARISH IN LOUISINANA. THE CITY SLIDELL!
