great raven:
>>>Personally I think Mrs. Weasly was either freinds with Lily or 
used to go out with James because she's so overly fond of Harry.>>> 

Sue B:
>>If this was the case, surely she would have said so? Besides, I 
think she's several years older than Lily and James. Remember, she 
has a couple of sons in their 20s. I don't think James and Lily would 
have been old enough for that if they'd survived.>>

Lily and James were 21-2 when they died. We know this because JKR has 
mentioned in an interview that Snape was "35 or 36" during GoF. All 
this information can be found on the HP Lexicon (think there's a link 
on the homepage), which is worth a visit anyway. They've got 
timelines there showing that Bill Weasley was actually at school for 
some of the same period as MWPP+L+S.
 There's actually been some speculation on list that Molly and Arthur 
are in their seventies (because wizards age later - hence McGonagall 
being "a very spritely seventy", and black-haired, and DD being about 
150), based on a comment Molly makes about the Groundskeeper before 
Hagrid, who was at the school when she was there (Hagrid went 
straight into the job after being kicked out of school aged thirteen, 
although many prefer to speculate that he worked as an apprentice for 
some time). Molly and Arthur being around Hagrid's age or older makes 
sense when you consider that they essentially have two families, as 
there's quite a big age gap between Charlie and Percy.
So, no, Molly probably didn't go out with James. Unless she visited 
little Bill at school one year and developed a thing on the arrogant, 
bespectacled Head Boy...calling all Shippers. Take this thing off my 
hands, and quickly.

Kirstini, mildly disgusted with herself.
