Reilly
means valiant. Liked it on "Buffy", when it was her boyfriend's name, but I think it's better suited for a girl.
(my daughter's name) - I think this is a great Irish-sounding name, and I needed to carry on the Irish somehow, since I married a Scottish Swede!
Reilly Brianne just makes me think of a cute sweet little girl.
