I used to love it, and while I don't dislike it now it just strikes me as a little bit trendy. :-/ Also, I think it would constantly be mistaken for
Brendan,
Brandon, and even
Braden. People would be going through the list of Br--n names before realizing it was
Brennan. :b But maybe I'm just being cynical, lol. I like it better than
Brendan, and I definitely prefer
Brendan to
Brandon. It's name a bad name at all and I think it would sound very nice as a brother to
Mira.
