The house is still there (at least it was when I went not long ago
)
Do you mean Daisy, trisher? I think Violet is too old to do her matric. 
Actually, I think Daisy will be happier marrying Andy and they can take over the farm eventually, a career and spinsterhood was not necessarily something to aspire to in those days, more something that happened to those unlucky enough to have lost fiancés in WW1.
Intrigued by the hairstyles, too, I remember DM telling me how she cycled into the nearest town and got her hair cut short (like Lady Mary's I imagine), her mistress was most annoyed - Nanny should not have had her hair cut without permission! The next week her ladyship went and got hers cut in the same style.
