German name, female. Not to confuse with 'Maximilian', which is a boys name. Since there are literally 0,0001% of girls called Maximiliane, you can feel special if you know one. And even more special if you can call one your friend.
" My best friend's called Maximiliane"
"FOR REAL?! My grandma used to tell me about Maximilianes... I never thought they really existed"
"Hey, I'm Maximiliane"
"... Maximilian? But you're a girl.
...
Aren't you?"
