Perhaps you should try some spelling variations:
\"ottinger\" » \"pottinger\", \"gottingen\", \"luttinger\"
\"gottinger\" » \"gpottinger\", \"ggottingen\", \"gluttinger\", \"gottingen\"
\"ggottingen\" » \"gottingen\", \"goettingen\", \"gottinnen\"

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: ( ottinger or ( gottinger OR ggottingen )).
