Cohem, Oldenburg

I found the following statement in an obituary.

Mrs Tapphorn was born at Cohem, Oldenburg, Germany, on Nov. 26, 1825.

Any idea the correct name of the village?

Ronald J Repking
Flossmoor, Illinois

I could be:
- Bakum
- Carum (parish Bakum)
- Bahlen (parish Dinklage)
- Bokern (parish Lohne)
The origin of the Tappehorn/Tapphorn/Taphorn is a big farm in Dinklage-B�nne

I hope it helps,
