Re Pepper Family Assistance Requested

Am looking for any information about RICHARDSON PEPPER, his wife, MARGARET PATTON, and their family. Richardson was a blacksmith in Ireland when they immigrated and landed in New Orleans. Have not located any naturalization records, passenger lists, etc. Please see my post in Journal for more info on this family. Any help would be most appreciated, particularly lookups in Court records.

They may be listed as: Richardson Papper, Marguerite Padne
