These caught my attention:
Arlette: this does feel remarkably early Hollywood. Curly hair, 1920s dress, singing in a café? Arletta would actually be very pretty.
Bertha: one of these undeniably ugly names it's very hard to see the appeal of. It makes me think of Rochester's first wife in
Jane Eyre.
Cesare: makes me think of
Cesare Borgia. It's lively, but scheming.
Grigory: this, in turn, makes me think of Rasputin. Scheming, but in a cantankerous way.
Sergius: cold, stern, all of its forms feel very Russian. I once met Polish siblings named
Sergiusz and
Natasza - I wonder if they had any Russian heritage. Both are Polish names, but with an undeniably Russian feel.
