Hi
I'm Swiss and I also think that Mullenger is not a Swiss surname.
The "Swiss Surnames Dictionary" only lists the surnames with place of origin, which still existed at this places in the 20th century. So it is possible that there existed other surnames at a certain place in the 18th century, which didnt't exist anymore at the same place in the 20th century. Also the place of origin must not be the same as the place of birth or the place where someone lived.
Regards
