I went to college with a female Brennan, and that's my only IRL association with the name. However, after researching it I've realized it's traditionally a boy's name. We are having so much trouble with girl names that we both like, and while we both like this name, I don't like it enough to perpetuate the boy names for girls trend.
What are some girl names that are similar to Brennan? Our last name is one syllable, ending in s, and of Scottish origin. We seem to prefer Irish, Scottish, British, and Welsh names.
Re: Names similar to Brennan
How about Brynn or Brenna?
I know a couple of girl babies with these names, and they could be a good option for you if you like Brennan.
I really like the name Brenna. I believe it's Irish or Scottish. I knew a girl named Brenna in high school and she was really sweet, so I have a good association with it.
There is also the more American-ized Brianna or Breanna. Or John Edwards' mistress's name is Brielle.

ETA: And I think it's great you're avoiding the boy name for girl thing. Brennan is definitely all boy to me, and I'd be confused if I met a female Brennan (and wonder why they didn't go for Brenna... I also happen to know both a Brennan and a Brenna - male and female respectively).
