2 gustav » 8 gustav, f gustav, dr gustav
_ gustav » _ gustavus
294 1828 » 1794 1828, 2 1828, 4 1828

2f 1878 » 28 1878, 29 1878, 2d 1878
29 1828 » 2 1828, 29 1829, 19 1828

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: %22stresemann%((2 gustav) OR (_ gustav)) %((((2f 1878) OR (((29 1828) OR (294 1828))))) OR (((28 1873) OR (28 1840))))-1929%22.
• The words AND, OR and NOT may confuse the search; try adding quotes: "%22stresemann%((2 gustav) or (_ gustav)) %((((2f 1878) or (((29 1828) OR (294 1828))))) or (((28 1873) or (28 1840))))-1929%22".
• Adding a wildcard symbol may retrieve word variants: %22stresemann%((2 gustav) or (_ gustav)) %((((2f 1878) or (((29 1828) OR (294 1828))))) or (((28 1873) or (28 1840))))-1929%22*.
