Perhaps you should try some spelling variations:
"george dyes hevesy" » "george hayes hevesy", "george de hevesy", "george die hevesy"
"george der hevesy" » "george de hevesy", "george dr hevesy", "george elder hevesy"
"george dyer hevesy" » "george dye hevesy"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("george dyer hevesy") OR ("george der hevesy"))) OR ("george dyes hevesy")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"george dyer hevesy\") OR (\"george der hevesy\"))) or (\"george dyes hevesy\"))".
• Removing quotes may allow a broader search: (((( george dyer hevesy ) OR ( george der hevesy ))) or ( george dyes hevesy )).
• Adding a wildcard symbol may retrieve word variants: (((("george dyer hevesy") OR ("george der hevesy"))) or ("george dyes hevesy"))*.
