I love Sirius also,if my next one is a boy i'm going with it!
I like Sirius as a boy's name, I think if I ever had a boy I might use it though. I love Ariadne and Lyra for girls. I thought Lyra would fit it with my dd who is named Lillian, a derivative of Lilith, the first woman. But I'm not sure if anyone would ever figure out the reference, lol.
