The name Jennerjohn is most likely coming from Mecklenburg as a variation of Jennerjahn, which can be found much more often.

Dutch

Dutch, most likely. Possibly, Swedish or Finnish.

I think Otten is Dutch and Jennerjohn is German. I tried on some Genealogy sites and it seemed to be this way

German or something close to it
