Were the Weasleys (particularly Molly) in the 1st OOP?

    OK, first of all, let me start out that JKR never actually said that 
Harry Potter performed the act of bodily elimination. I would not think 
that anybody could say that this means that Harry never took a crap in 
his 6 years at Hogwarts and one year on the run (and frankly, I'd just 
as soon not know how such arrangements worked when the Trio were 
camping, For all I know, Hermione waved a wand and said, "Excrementous 
Eliminatus!").

    In other words, just because JKR didn't say anything about it 
doesn't mean that it didn't happen.

    So, here's the thing. I personally believe that, although she wasn't 
in the Moody photo, I don't recall anything that says that Molly (or 
Arthur, for that matter) was not in the original Order of the Phoenix. I 
kind of assumed that she was, considering how the old hands, including 
DD, allowed her to take a leadership role in at least the organizational 
end of the 2nd OOP. Now, it could be just her personality that caused 
others to defer to her, or willingness to accept her as an equal because 
she's on their side, but she does seem to be no stranger to such things. 
Perhaps it was by proxy; note that Arthur doesn't even seem to be core 
in the 2nd Order. But I still have a feeling that it is at least implied 
that she was a member of the 1st Order. Anybody have any specific ideas 
one way or the other (or is there canon I missed which specifies that 
she wasn't)? If there is no specific canon, are there any hints?
