great brittain » great britain, great britian, great britain's
et colonies » her colonies, des colonies, les colonies

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 (zgreat britain))) OR (great brittain)) %((((((4 colonies) OR (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 (zgreat britain))) or (great brittain)) %((((((4 colonies) OR (p colonies))) or (_ colonies))) or (et colonies)) %trf administration%22".
• Adding a wildcard symbol may retrieve word variants: %((((22great britain) or (zgreat britain))) or (great brittain)) %((((((4 colonies) OR (p colonies))) or (_ colonies))) or (et colonies)) %trf administration%22*.
