Perhaps you should try some spelling variations:
"alexander innes filler" » "alexander irvine filler", "alexander inner filler", "alexander inner filter"
"alexander de miller" » "alexander d miller", "alexander duke miller", "alexander dow miller", "alexander der miller", "alexander de mille"

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: (("alexander innes filler") OR ("alexander de miller")).
• Removing quotes may allow a broader search: (( alexander innes filler ) or ( alexander de miller )).
• Adding a wildcard symbol may retrieve word variants: (("alexander innes filler") or ("alexander de miller"))*.
