Perhaps you should try some spelling variations:
eberhardt » ebgerhardt (Expand Search)
erhard » gerhard (Expand Search)
ggerhardt » gggerhardt (Expand Search), gerhard (Expand Search), gerhart (Expand Search), ggerhard (Expand Search)
gerhardt » ggerhardt (Expand Search), gerhard (Expand Search)
gebhardt » gerhard (Expand Search)
ggerhart » gerhart (Expand Search), gerhard (Expand Search)
finckh" » finck" (Expand Search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((eberhardt OR erhard) OR ((ggerhardt OR gebhardt) OR (ggerhart OR gerhardt))) (finckh\" OR fink\")~".
• Removing quotes may allow a broader search: ((eberhardt OR erhard) OR ((ggerhardt OR gebhardt) OR (ggerhart OR gerhardt))) (finckh OR fink )~.
• Adding a wildcard symbol may retrieve word variants: "((eberhardt OR erhard) OR ((ggerhardt OR gebhardt) OR (ggerhart OR gerhardt))) (finckh" OR fink")*.
