I can provide details about following title as given by Karl Petersen
in the 15.11.25 MMD:

	"6. Waltz, La grande duchesse de Gerolstein?, Jacques Offenbach?
	-1867.  Perhaps this has a yearning for home too, but I haven't
	found the libretto to review. Anyone?"

I confirm this is taken from the opera-bouffe La Grande-duchesse de
Gerolstein (1867) by Offenbach.  This is not a waltz, but a fragment of
a duet in Act I: no. 2L Duo de Fritz et Wanda (the movement is the aria
of Wanda)

You can hear the complete duet here (the fragment is starting at 44
sec.): https://www.youtube.com/watch?v=MdluFpNqJns
