I love the name and I don't think it's too close to the other name, either.
I just wanted to say, I totally agree with you on not telling people the name you have chosen. When I was pregnant, we made up fake baby names (Mable and Rambo) just as a joke to tell people when they asked.. we told them it was a joke, of course, and that we were choosing not to tell anyone. We said that whatever name we DO decide on, will sound better to our families than our "joke" names!
