Perhaps you should try some spelling variations:
"elizabeth morgan" » "elizabeth margaret", "elizabeth mary", "elizabeth mure"
"elizabeth morice" » "elizabeth mure", "elizabeth mary"
"elizabeth moxon" » "elizabeth foxon", "elizabeth moon", "elizabeth oxon"

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: (((("elizabeth morgan") OR ("elizabeth morice"))) OR ("elizabeth moxon")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"elizabeth morgan\") OR (\"elizabeth morice\"))) or (\"elizabeth moxon\"))".
• Removing quotes may allow a broader search: (((( elizabeth morgan ) OR ( elizabeth morice ))) or ( elizabeth moxon )).
• Adding a wildcard symbol may retrieve word variants: (((("elizabeth morgan") OR ("elizabeth morice"))) or ("elizabeth moxon"))*.
