"The odd thing, Harry, is that it may not have meant you at all. Sybill's prophecy could have applied to two wizard boys, both born at the end of July that year, both of whom had parents in the Order of the Phoenix, both sets of parents having narrowly escaped Voldemort three times. One, of course, was you. The other was Neville Longbottom."
-- Albus Dumbledore (OP37)
Neville, like Harry, is born to parents who are fighting against Voldemort. They are famous Aurors, Frank and Alice Longbottom.
Neville was born just "hours" before Harry (YL).
