Unfortunately, schools will not give out names of former students as they respect the privacy of their families. I also tried to do a facebook and google search with no initial luck. Linked In usually has professional's colleges but not high schools unless they just graduated and I was not able to find her there as well.
If possible, I would suggest trying to find a yearbook of the years you think she went there and look her up.
