It's a great name got a very beautiful meaning too, derives from the latin term clareo meaning I am bright, I shine (which considering your signature seems very appropriate somehow). My first instinct was isn't it spelled Claire but the name website tells me that's the French spelling, so it wasn't so strange on my part to think that, having lives in francophone countries/regions for a good chunk of time.
Yea, part of the reason I chose it is because it is an Irish name, and I kind of want to keep my first name Irish sounding.
It is a nice name but I personally find it difficult to pronounce correctly. Have you considered Clara? 愛
This is a very opinion based question. I think that Clare is a good name, but in the end what matters is that you think that it is a good name. As long as you think that this is the name that will fit you, that is what matters.
I think Clare is wonderful, and it sounds like you think so as well. Which is all that matters, really.
