What branch of Christianity do I belong?

I was not raised in a religious household, but now that my daughter is four I want to start attending church/sunday school ect. I have no idea what I should be looking for. I did go to a Lutheran church briefly as a child, but I dont think that should be the basis for my new church. Id prefer to choose for believe purposes. What are the differences in belief? I know they all interpret the bible differently ect.
