    My impression is that Sibyll was hired at the time of the prophesy. 
Snape was still in Voldemort's camp and passed on the prophesy. It would 
then have taken V. some time to determine what child was the prophesied 
danger. Harry was 15 months old when his parents were killed and 
Voldemort fell. We know that someone, possibly Snape, reported that 
there was a spy in the Order a year before Voldemort fell. We are also 
encouraged to believe that Snape, in some way tried to warn James about 
Sirius, Snape's suspect, and James refused to believe it. Snape may have 
tried to warn Lily. We don't know how long the Potters were in hiding 
before Wormtail turned them over to Voldemort. Sirius might have been 
their secretkeeper for a while until he decided it was safer to pick 
someone that Voldemort would never expect. Since Snape was teaching for 
fourteen years in OotP, when Harry is fifteen, we know that Snape 
started teaching when Harry was a year old give or take a month here or 
there. Three months later Voldemort was Vapormort.
