I'm needing to know all of the members of the original Order of the Phoenix and a comparative list of the members in the newly formed Order, or at least, the Order as of book 5.

I've realised in my recent writings that I've been assuming anyone in the more recent Order who is in their late thirties or older was also in the original organisation. I've also recently realised that doesn't seem to be the case, does it?

Hopefully I can be directed to a list or better yet, lists, somewhere... Otherwise, I'll need help in compiling my own!

Also, concerning the Marauders: Is it safe to say they joined the Order almost immediately upon leaving Hogwarts?

I'm a bit out of touch with canon, as you can see.
