Perhaps you should try some spelling variations:
"anna margarete anstruther" » "anna margaretha anstruther", "anne margaret anstruther", "sanda margareta anstruther"
"ann margaret anstruther" » "anne margaret anstruther", "ann margret anstruther", "anna margaretha anstruther"

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: "((\"ann margaret anstruther\") OR (\"anna margarete anstruther\"))".
• Removing quotes may allow a broader search: (( ann margaret anstruther ) OR ( anna margarete anstruther )).
• Adding a wildcard symbol may retrieve word variants: (("ann margaret anstruther") OR ("anna margarete anstruther"))*.
