Le droit d'aînesse
Governor Folbach must provide an heir to receive a patent of nobility. His nephew Tancred is captured by gypsies, while his niece Falka elopes with Arthur and disguises herself as Tancred to attend the Governor. Mistaken identity sets the gypsies and the Governor's arranged marriage plans against her; eventually Falka is pardoned and made heir, and Tancred marries Edwige, the gypsy chief's sister.
