I may adopt a little boy and a little girl (I can do that, right?)

I don't remember the little girl I adopted lt time, but I liked her. She was nice. I think she was from Whiterun, but I may be lying.

I want a nice, respectful boy, and a young, ambitious boy.

Suggestions, please?

I think there was a little boy in dawnstar, i think? who lost his parents and helps around the dock or something I don't know
