Searching for my father Rudolf Petzold

Hello,

I have earlier been on this list to search for my father, Rudolf
Petzold, who died in Nordstemmen in 1953 but was recorded in Northeim
according to German Red Cross.
I have contacted the B�rgerb�ro/Standesamt in both Nordstemmen and
Northeim but they can't find any death-records.
Where can I go now?

My father

born 17.02.20 possibly in Hildesheim/Alfeld(Leine)
death 22.03.53 in Nordstemmen

Greetings

Rudolf Petzolt
