Auersperg, Furst J von 18??-?? Bohemia, ? - Bohemia or Austria, ?
Graf J von Auersperg, 'von Auersperg' being a family name, not the name of a city or county (although originating from an ancestral castle Auersperg), the family had many branches with many members titled Graf and among them several with an initial J (Johann, Josef), almost all of them amateur musicians, making it difficult to identify the composer of the listed work

possibly Graf Josef von Auersperg, 17.may.1850 arrived with his family from Bohemia at a 'Gasthofen' in Vienna Austria, 1851-1852 as forest owner Graf Josef von Auersperg contributed to the bohmischen Forstvereins ; 
he may have been a grandson or a son of Graf Josef von Auersperg (Prague 1767-1829 Brunn/Brno) lawyer, senior district judge and regional court president in Prague and owner of Schloss Hartenberg, including a theatre, near Falkenau an der Eger (Sokolov), a man of science, owner of a large important library, on his invitation Goethe celebrated his 70th and 72nd birthday there

Johann Hoffmann founded his music publishing house on 1.feb.1839, after his death in 1849 continued by his widow as Joh. Hoffmann's Wwe and after her death by their children still as Joh. Hoffmann's Wwe, so the 'Alte Jagdfanfare' probably dates from any year after 1849 and certainly before 1906 when it was listed in Pazdirek
