Any suggestion on how to locate a person from her maiden name . I have maiden name, school and year of graduation from high school and last city seen in 5 years ago.
Is there a way to find the married name from the maiden name?

If she is in the U.S. you could try Find a Friend - High School Military College Class Reunions (http://www.classmates.com/) Another site to try would be The Web's Largest People Search by Background Check, Public Records Search, E-Mail Address - Find People and Search Business at PeopleFinders.com (http://www.peoplefinders.com/?CMP=Google&gclid=CJzBh82kmZMCFRYcagod7yGqwQ) married as along with maiden names are listed frequently there.

If she has not registered there may be others from her class who know of her whereabouts. The class Register should have all the info you need.
