It's very very weird that they repeated a name.
Isn't there another way they could've honored him again other than repeating?
I have to agree! I was a bit disappointed after seeing Louis (I thought it was Lou-is but Lou-ee sounds nicer with the middle names) and Charles, because they had already use Louis and Charlotte. I'm also not a fan of Charles but at least, it's better than Albert, from my point of view.
It would be sweet if they used Louis as a third middle name, like in George's name. It would be a cute connection between siblings. However, as a first name it takes some individuality away from Prince Louis, in my opinion, despite George's middle names not being frequently mentioned.
I do love Arthur, it would have been an handsome first name!
