with the cases of
Matilde and
Asia being not comparable.
About
Asia, my contact sent me more information this morning: "
Asia Argento is actually
Aria. The name
Asia was refused by the registry office in 1975 when she was born.
Only in 2001-2 the naming laws no longer proibited geografical names. in this case it's likely people got the idea from the Argento family."
