Greg's notes: the public records show that this address is Nancy L Kirchgessner, born in 1960. Our class mate would obviously not be born in 1960, and would be be Nancy A or Nancy R depending on whether she chose to use her maiden name or her original middle name (Ann).
On the other hand, I can't find any other Nancy Kirchgessners. Not one in the entire USA, so I'm lost on this one. Check this out!
