In the annual tables for records at the Paris Archives (http://archives.paris.fr/s/6/tables-annuelles/?), I have found some records where the Numéro de l'acte (record number) includes the letters "Ter" - for example "541Ter" (in 1946 deaths, 16th arrondissement, for Paul Georges Marie LECAT). Most other index entries just have a number (no letters).
If I try to find this death record using just the number 541 in the Actes d'état civil (http://archives.paris.fr/s/4/etat-civil-actes/?), the record with that number does not pertain to the the right person.
Does anyone know how to use the record numbers including the letters "ter" in the index table to look up the actual (death) record?
