I have restarted my game since Seasons release probably 5 or 6 times now, and until just last week, I had always had twin girls. I was shocked to get a boy and girl this time.
I named mine Brian and Serenity. I had to think of something off the cuff all of a sudden because I had to change it from my normal Sierra and Serenity. :D
I follow a "pattern" of names in that family. The males have very average names and the females (except Dora) start with S.
