my dad is looking for a woman from long ago?

my dad, (age of 45) is looking for a girl he used to know in his high school in 1984 or 1983 (he cant remember). sadly, he only knows her first name (laurel) and that she went to perry meridian high school in Indiana...is there any way i would be able to find this woman without knowing her last name? he also knows the city she lives in, since he saw her four or five years back but didn't realize it was her until it was too late. i have no idea what his affiliation with this person is but it must be important as he's paying me for finding her xD (no sexual comments or anything about her being my mom or stuff please) thanks.
