I'm not a big fan of made up names, so my dislike of Reonie won't come as much of a surprise.
Apart from being made up, I find it annoying. My brain keeps wanting to process it as
Leonie. But my eyes won't let it. Not good. I see
Leonie so rarely here in the U.S. and now it's being *tampered* with.
Some combined names work. I love
Hannelore, for example. But Reonie gets thumbs down from me, sorry.
