22great britain » zgreat britain, great brittain, great britains
xgreat britain » zgreat britain, great brittain, great britains
et colonies » her colonies, des colonies, les colonies

Try widening your search to All Fields.

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: %((((22great britain) OR (great britain))) OR (xgreat britain)) %((((p colonies) OR (_ colonies))) OR (et colonies)) %trf administration%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%((((22great britain) or (great britain))) or (xgreat britain)) %((((p colonies) OR (_ colonies))) or (et colonies)) %trf administration%22".
• Adding a wildcard symbol may retrieve word variants: %((((22great britain) or (great britain))) or (xgreat britain)) %((((p colonies) OR (_ colonies))) or (et colonies)) %trf administration%22*.
