Tom at Hogwarts with James' Parents

aussie:
Did James' parents go to Hogwarts at the same time as Tom Riddle?
How likely is that?
What implications are there?

Snape's mother had a potions book that came out the same time Tom was 
at Hogwarts, so the age would be about right for James' parents to 
have been there too.

Maybe other families that rivalled Tom Riddle during his school years 
were the reason so many families seemed to be almost wiped out ... 
(eg. Bones)

When Voldemort had the choice of going after the Potters or the 
Longbottoms, could that have influenced his decision?
