the answer is a bit difficult. There are 5 Holtorf, all situated in the former Kingdom of Hannover and now they are all part of another town or village:
Holtorf now part of Colnrade,
But there exists no Korzern in Germany.
Probably your Holtorf is that near Schnackenburg. Nearby exists a village named Kapern.
The church is:
Ev.-luth. Pfarramt Schnackenburg
Great success and greetings
