Maximilian: a majestic name with an approachable nickname. I like it.
Elisabetta Marie:
Elisabetta isn't my cup of tea, and
Marie is frightfully boring.
Amedeo Marie Joseph Carl Pierre Philippe Paola Marcus:
Amedeo is enchanting. I actually prefer
Marie for a man (as a middle name).
Paola, on the other hand, reminds me more of a Spanish peasant girl than a Belgian monarch.
Anna Astrid: I like both names, but they don't go with each other.
