<<At that time 2 of the Weasley kids have already graduated Hogwarts,
so the oldest is probably almost 20, which means that his parents are
probably around 40, so at least 7 years difference in age between Lupin
and Mrs. Weasley is about right. >>

>From GoF, we know 2 things: 1. Bill graduated Hogwarts at least 5 years
before the last task, because he says he hasn't been in the Hall in
over five years; and 2. Mr & Mrs Weasley were there at the same time,
but not necessarily in the same year, beause Mrs Weasley mentions a
moonlit stroll they took.
Assuming Bill graduated at 18, then he is at least 23 (i.e. about 10 years
older than Ron & Harry), which would imply that Mrs Weasley is likely at
least 10 years older than the older of Harry's parents (have we ever even
seen anything to say that Lily was younger than James? I don't think so)
