Perhaps you should try some spelling variations:
"elizabeth throgmorton" » "elizabeth thompson"
"elizabeth thomson" » "elizabeth hanson", "elizabeth thomas", "elizabeth thurbon"
"elizabeth morton" » "elizabeth moreton", "elizabeth moxon", "elizabeth morgan"

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