Perhaps you should try some spelling variations:
thomas nicholson » thomas richardson, james nicholson, thomas thomson
thomas dickson » thomas jackson, thomas dawson, thomas denison
1st baronet » 1st baroness, 1st baron, first baronet

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: "\"((\\"sir ((thomas nicholson) OR (thomas wilson)), 1st baronet\\") or (\\"sir thomas dickson, 1st baronet\\"))\"".
• Removing quotes may allow a broader search: (( sir ((thomas nicholson) OR (thomas wilson)), 1st baronet ) or ( sir thomas dickson, 1st baronet )).
