Perhaps you should try some spelling variations:
2 gustav » 8 gustav, f gustav, dr gustav
_ gustav » _ gustavus
28 1843 » 28 1840, 28 1842
28 1874 » 28 1824
28 1873 » 28 1833
2f 1878 » 28 1878, 29 1878, 2d 1878
29 1828 » 294 1828, 2 1828, 29 1829

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 (((((28 1873) OR (28 1874))) OR (28 1843))))-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 (((((28 1873) OR (28 1874))) or (28 1843))))-1929%22".
• Adding a wildcard symbol may retrieve word variants: %22stresemann%((2 gustav) or (_ gustav)) %((((2f 1878) or (29 1828))) or (((((28 1873) OR (28 1874))) or (28 1843))))-1929%22*.
