Who Are The Seven Archangels?

I love learning about biblical events and about different religons. But when you google the 7 archangels, every website and person says something different, but every website can agree on four. Michael, Gabriel, Raphael, and Uriel. But I want to know the others. The other three are practically unknown because no one knows who they are. It doesnt matter, I'm not doing a report on it or whatever, but it'd be an interesting thing to know. Anyone have an ideas?:].
